In this article, we will explore the equation y=x2y = x^2 and use it to complete a given table. We will then plot the points on a graph and determine which graph best represents the equation.

The Equation y=x2y = x^2

The equation y=x2y = x^2 is a quadratic equation that represents a parabola. The graph of this equation is a U-shaped curve that opens upwards. The equation can be rewritten as y=xβ‹…xy = x \cdot x, which shows that the value of yy is equal to the product of xx and itself.

Completing the Table

To complete the table, we need to substitute the values of xx into the equation y=x2y = x^2 and calculate the corresponding values of yy.

Let's start by substituting the value of x=βˆ’3x = -3 into the equation:

y=(βˆ’3)2y = (-3)^2

Using the order of operations, we first evaluate the exponent:

(βˆ’3)2=βˆ’3β‹…βˆ’3=9(-3)^2 = -3 \cdot -3 = 9

So, the value of yy when x=βˆ’3x = -3 is 9.

x y
-3 9

Next, let's substitute the value of x=βˆ’1x = -1 into the equation:

y=(βˆ’1)2y = (-1)^2

Using the order of operations, we first evaluate the exponent:

(βˆ’1)2=βˆ’1β‹…βˆ’1=1(-1)^2 = -1 \cdot -1 = 1

So, the value of yy when x=βˆ’1x = -1 is 1.

x y

Now, let's substitute the value of x=0x = 0 into the equation:

y=(0)2y = (0)^2

Using the order of operations, we first evaluate the exponent:

(0)2=0β‹…0=0(0)^2 = 0 \cdot 0 = 0

So, the value of yy when x=0x = 0 is 0.

x y
-3 9

Next, let's substitute the value of x=1x = 1 into the equation:

y=(1)2y = (1)^2

Using the order of operations, we first evaluate the exponent:

(1)2=1β‹…1=1(1)^2 = 1 \cdot 1 = 1

So, the value of yy when x=1x = 1 is 1.

x y
-3 9
-1 1
0 0

Finally, let's substitute the value of x=3x = 3 into the equation:

y=(3)2y = (3)^2

Using the order of operations, we first evaluate the exponent:

(3)2=3β‹…3=9(3)^2 = 3 \cdot 3 = 9

So, the value of yy when x=3x = 3 is 9.

x y
-3 9
-1 1

Plotting the Points on a Graph

To plot the points on a graph, we need to use a coordinate plane. The x-axis represents the values of xx, and the y-axis represents the values of yy.

1 1
3 9

Plotting the points on the graph, we get the following:

  • The point (-3, 9) is plotted on the graph.
  • The point (-1, 1) is plotted on the graph.
  • The point (0, 0) is plotted on the graph.
  • The point (1, 1) is plotted on the graph.
  • The point (3, 9) is plotted on the graph.
