Step-by-step explanation:
Just sub 4 into where n is
I don't know what you mean by "critical points". However, I'm going to list all the important points in this equation-
x intercepts: (-1 ,0) and (5,0)
vertex: (2,-9)
y intercept: (0,-5)
Hope this helps!

Answer:
x ≈ 136.7 ft
Step-by-step explanation:
As you have marked, the relevant sides are the adjacent side and the hypotenuse. The mnemonic SOH CAH TOA reminds you ...
Cos = Adjacent/Hypotenuse
For this triangle, that means ...
cos(43°) = (100 ft)/x
x = (100 ft)/cos(43°) . . . . . . . . . . multiply both sides by x/cos(43°)
x ≈ 136.73 ft
The length x is about 136.7 feet.
