Explanation:
Let's start by choosing a range of values for x. For example, we can use x = -2, -1, 0, 1, and 2.
Substituting these values into the equation, we get:
For x = -2:
y = (-2)^2 - 4(-2)
y = 4 + 8
y = 12
For x = -1:
y = (-1)^2 - 4(-1)
y = 1 + 4
y = 5
For x = 0:
y = (0)^2 - 4(0)
y = 0 - 0
y = 0
For x = 1:
y = (1)^2 - 4(1)
y = 1 - 4
y = -3
For x = 2:
y = (2)^2 - 4(2)
y = 4 - 8
y = -4
Thus, the completed table of values for y = x^2 - 4x is:
x | y
-2 | 12
-1 | 5
0 | 0
1 | -3
2 | -4
Each value of x is substituted into the equation, and the corresponding value of y is calculated. These values represent points on the graph of the equation. By plotting these points and connecting them, we can visualize the shape of the graph, which is a downward-opening parabola.
