Answer:

Find the attached

Step-by-step explanation:

We have been given the following functions and required to graph them;

y=(x+4)(-x+64)

Y=-x^2+68

We can expand the expression in the first equation;

(x+4)(-x+64)  = -x^2+64x-4x+256 = -x^2+60x+256

The first equation can thus be written as;

y = -x^2+60x+256

We can now proceed to employ graphing utilities such as desmos graphing to plot these two equations on the same graph;

y = -x^2+60x+256

Y=-x^2+68
