Solve for the inverse of: f(x)=1/8(x+1)^3

lara31 [8.8K]

Answer: $y=(8x)^{\frac{1}{3}} -1$ or $y=\sqrt[3]{8x} -1$

Step-by-step explanation:

To find the inverse, you switch y with x and x with y. Then, you solve for y.

$y=\frac{1}{8} (x+1)^3$ [switch y with x and x with y]

$x=\frac{1}{8} (y+1)^3$ [multiply both sides by 8]

$8x=(y+1)^3$ [cube both sides]

$\sqrt[3]{8x} =y+1$ [subtract both sides by 1]

$y=\sqrt[3]{8x} -1$ or $y=(8x)^{\frac{1}{3}} -1$

Answer:

6.) -3.544

Step-by-step explanation:

6.2(x+3.5)-x =6.2x+21.7 -x =6.2x-x+21.7 =5.2x+21.7

-3(6-2x) =-18(+-)6x =-18-6x

5.2x +6x=-18-21.7

11.2x=-39.7

x=-39.7÷11.2

x=3.544
