Answer:
f(x) = 3x^4 – 48.
x=2,-2
Step-by-step explanation:
X=2 because (-8x+117)=101 if x=2 -8*2=-16. -16+117=101

Answer:
f(8) = -30 is the maximum
Step-by-step explanation:
The equation is that of a parabola in vertex form:
y = a(x -h)^2 +k . . . . . . . . (h, k) is the vertex; 'a' is the scale factor
Comparing this form to the given equation, we have ...
f(x) = -(x -8)^2 -30
That is, the scale factor is -1, and the vertex is (8, -30).
When the scale factor is negative, the graph opens downward and the vertex is a maximum. The maximum value is -30.
Would this be the correct answer? If not, can you further explain the question?(11x+8y)(11x-8y)
