Answer:
i don't know, you need to tell us what we need to do
Step-by-step explanation:
4x = y
2x^2 - y = 0
2x^2 - 4x = 0
2x(x - 2) = 0
2x = 0 or x - 2 = 0
x = 0 or x = 2
y = 4(0) or y = 4(2)
y = 0 or y = 8
Therefore, solution set is {(0, 0), (2, 8)}
Divide everything by 4 getting:
7y=3x+21
then get all of the variables on one side by subtracting 3x:
7y-3x=21
F(x) = x + 3
y = x + 3
x = y - 3
Inverse is h(x) = x - 3
