So I know it is a parabola and you have to find the slopes to somehow get to my answer.
I am not sure if it is concave up or down.
Just graph the slope at every point lol
So I find the slopes at the points and then I graph them?

nah you can roughly graph it from f(x)
When f(x) is decreasing, f'(x) will be negative, when f(x) is increasing, f'(x) will be positive.
