Answer:
Explanation:
You might start by making a table of x and y values:
x y
0 0
1 1
-1 1
2 4 and so on.
That coefficient (1/2) will halve all of the y values, so that you'll have:
x y/2
0 0/2 = 0
1 1/2 = 1/2
-1 1/2 = 1/2
2 4/2 = 2 and so on.
The graph will have a parabolic shape, and this parabola will open up. The graph is flatter than that of y = x², due to the coefficient 1/2.
