Answer:
Answer is - 2.
Step-by-step explanation:
(f+g) (x)=f(x) +g(x)=x^2 -2x +6x+4
=x^2 +4x+4=0
If x=-4, then (f+g) (-4) =16-16+4=4
if x=-2, then (f+g) (-2)=4-8+4=0
Answer: C
Step-by-step explanation:
Volume = wlh=x^3
surface area= 6x^2
x^3=6x^2
Divide by ^2 on both sides
x=6
The y-intercept of the function is at y = -3 so the options that don’t include it are off the table. The only possible answer is option C. Option A doesn’t work because plugging in positive values would give negative numbers within the square root which isn’t defined in the real numbers.
