To find the y-value that corresponds to the x-value of -1 for the function \( f(x) = 2x^2 - 2x \), we need to substitute -1 into the function.

Calculate \( f(-1) \):

\[
f(-1) = 2(-1)^2 - 2(-1)
\]

First, calculate \( (-1)^2 \):

\[
(-1)^2 = 1
\]

Now substitute this back into the function:

\[
f(-1) = 2(1) - 2(-1)
\]
\[
= 2 - (-2)
\]
\[
= 2 + 2
\]
\[
= 4
\]

Thus, the y-value that corresponds to the x-value of -1 is \( 4 \).
