What would be f(-1), f(2), and the multiple answers for f(x)=-2x?

The graph is very blurry/fuzzy. So it's hard to tell and be 100% certain.

Draw a vertical line through -1 on the x axis. This vertical line looks like it crosses the curve at (-1,1). If that is the case, then f(-1) = 1

Draw a vertical line through 2 on the x axis. This vertical line looks like it crosses the curve at (2,2). If that is the case, then f(2) = 2

notice how the outputs of the function are equal to the y coordinate of the point of intersection between the vertical line and the curve.
