You are supposed to find the derivativ graph without actually direcly calculating the derivative.
Somebasic knowledge about functions is required. For example what basic formula a parabola follows.
Look at the slopes at chosen oints and you can see that the slope of that tangent is always numerically smaller (negative on the left side) than the one for a bigger x. Now see that the grap is symmetrical and apply the basic formula for a parabola.

The slope of your derivative is too high desu. I think
