Question 1: Function Analysis

Understanding the Function

We are given a function $f(x) = x^3 + 1$. To analyze this function, we need to understand its behavior and properties. The function is a cubic function, which means it has a degree of 3. This implies that the function will have a cubic shape, with a single inflection point.

Key Properties of the Function

• Domain: The domain of the function is all real numbers, denoted as $(-\infty, \infty)$.
• Range: The range of the function is also all real numbers, denoted as $(-\infty, \infty)$.
• Degree: The degree of the function is 3, which means it is a cubic function.
• Inflection Point: The function has a single inflection point, which is the point where the function changes from concave to convex or vice versa.

Finding the Inflection Point

To find the inflection point, we need to find the second derivative of the function and set it equal to zero.

Step 1: Find the First Derivative

The first derivative of the function is:

$$f'(x) = 3x^2$$

Step 2: Find the Second Derivative

The second derivative of the function is:

$$f''(x) = 6x$$

Step 3: Set the Second Derivative Equal to Zero

To find the inflection point, we set the second derivative equal to zero:

$$6x = 0$$

Solving for $x$, we get:

$$x = 0$$

Therefore, the inflection point of the function is $x = 0$.

Conclusion

In conclusion, the function $f(x) = x^3 + 1$ is a cubic function with a single inflection point at $x = 0$. The function has a domain and range of all real numbers, and its degree is 3.

Answer

The inflection point of the function $f(x) = x^3 + 1$ is $x = 0$.

To find the inflection points, we set the second derivative equal to zero:

$$12x^2 + 12x + 6 = 0$$

Solving for $x$, we get:

$$x = -\frac{1}{2}$$

Therefore, the inflection points of the function are $x = -\frac{1}{2}$, $x = 0$, and $x = 1$.
