Question

Find a formula for the inverse of the following function, if possible.

Answer 1

\[k(x) = (5x + 4)^{\frac{ { 1 } }{ 5 }}\]

\[k ^{-1} (x) = \]

does not have an inverse function

Answer 2

1/(5x + 4)^4/5

Answer 3

is this right

Answer 4

Answer 5

No. After you switch x and y, you get

x = (5y + 4)^1/5

To solve for y, you need to take everything to the power of 5 to get rid of the 1/5

\( x = (5y + 4)^{\frac{1}{5}}\)

\( x^5 =( (5y + 4)^{\frac{1}{5}})^5\)

\( x^5 =5y + 4\)

Can you solve for y now?
