If that's the side length, s, then cube 4x^2+3 to obtain the cube volume:
V(x) = (4x^2+3)^3 (answer)
Answer:
f^-1 (x) = x/5
Step-by-step explanation:
f(x) = 5x
Replace f(x) with y
y= 5x
Exchange x and y
x = 5y
Solve for y
Divide each side by 5
x/5 = 5y/5
x/5 = y
The inverse is x/5
The correct answers are:
B, D, & E
This is because 20% of 45 is 9
and
1/5 * 45 = 9
20/100 * 45 = 9
0.2 * 45 = 9
