Introduction
In this article, we will evaluate the function f(x) = x^2 - 3 at the indicated values of x. We will calculate the values of f(-3), f(3), f(0), and f(1/2) and discuss the results.
Evaluating f(-3)
To evaluate f(-3), we substitute x = -3 into the function f(x) = x^2 - 3.
f(-3) = (-3)^2 - 3 f(-3) = 9 - 3 f(-3) = 6
Evaluating f(3)
To evaluate f(3), we substitute x = 3 into the function f(x) = x^2 - 3.
f(3) = (3)^2 - 3 f(3) = 9 - 3 f(3) = 6
Evaluating f(0)
To evaluate f(0), we substitute x = 0 into the function f(x) = x^2 - 3.
f(0) = (0)^2 - 3 f(0) = 0 - 3 f(0) = -3
Evaluating f(1/2)
To evaluate f(1/2), we substitute x = 1/2 into the function f(x) = x^2 - 3.
f(1/2) = (1/2)^2 - 3 f(1/2) = 1/4 - 3 f(1/2) = -11/4
Conclusion
In this article, we evaluated the function f(x) = x^2 - 3 at the indicated values of x. We calculated the values of f(-3), f(3), f(0), and f(1/2) and discussed the results. The values of f(-3) and f(3) were both 6, the value of f(0) was -3, and the value of f(1/2) was -11/4.
Discussion
The function f(x) = x^2 - 3 is a quadratic function, which means it has a parabolic shape. The value of the function at a given point x is determined by the value of x^2 and the constant term -3. In this article, we evaluated the function at four different values of x and calculated the corresponding values of the function.

=============================================================
Q: What is a function?
A: A function is a relation between a set of inputs (called the domain) and a set of possible outputs (called the range). It is a way of describing a relationship between variables.
Q: What is the difference between a function and an equation?
A: An equation is a statement that says two expressions are equal, while a function is a relation between a set of inputs and a set of possible outputs. In other words, an equation is a statement, while a function is a rule.
Q: How do I evaluate a function at a given value?
A: To evaluate a function at a given value, you substitute the value into the function and simplify the expression. For example, if we have the function f(x) = x^2 - 3 and we want to evaluate it at x = 2, we would substitute x = 2 into the function and get f(2) = 2^2 - 3 = 4 - 3 = 1.
Q: What is the domain of a function?
A: The domain of a function is the set of all possible input values for which the function is defined. In other words, it is the set of all values that can be plugged into the function.
Q: What is the range of a function?
A: The range of a function is the set of all possible output values for which the function is defined. In other words, it is the set of all values that the function can produce.
Q: How do I determine if a function is even or odd?
A: A function is even if f(-x) = f(x) for all x in the domain of the function. A function is odd if f(-x) = -f(x) for all x in the domain of the function.
Q: What is the difference between a linear function and a quadratic function?
A: A linear function is a function of the form f(x) = ax + b, where a and b are constants. A quadratic function is a function of the form f(x) = ax^2 + bx + c, where a, b, and c are constants.

A: To graph a function, you can use a graphing calculator or a computer program. You can also use a table of values to plot points on the graph.
Q: What is the significance of the x-intercept of a function?
A: The x-intercept of a function is the point where the graph of the function crosses the x-axis. It represents the value of x for which the function is equal to zero.
Q: What is the significance of the y-intercept of a function?
A: The y-intercept of a function is the point where the graph of the function crosses the y-axis. It represents the value of y for which the function is equal to zero.
Q: How do I find the inverse of a function?
A: To find the inverse of a function, you can swap the x and y variables and solve for y.
Q: What is the difference between a one-to-one function and a many-to-one function?
A: A one-to-one function is a function that passes the horizontal line test, meaning that each value of y corresponds to exactly one value of x. A many-to-one function is a function that fails the horizontal line test, meaning that multiple values of x correspond to the same value of y.
