Graph the function: f (x) = 2x^2 - 2x. What is the y-value that corresponds to the x-value of -1

Answer 1

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

So we calculate:

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

Calculating each term:

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

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