Answer:
Find the attached
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
