Graph the function f(x) = 2x^2 - 2x. What is the y value that corresponds to the x-value of -1?
To find the y value that corresponds to the x-value of -1, we substitute x = -1 into the function f(x) = 2x^2 - 2x:
f(-1) = 2(-1)^2 - 2(-1)
= 2(1) + 2
= 2 + 2
= 4
So, the y value that corresponds to the x-value of -1 is 4.
