Question

PLEASE HELP ME

WHATS THE INVERSE NOTATION OF

f(x) = 3x^4 , x ≤ 0



PLEASE EXPLAIN

Answer 1

`f(x)^(-1) = \sqrt[4]{(x)/(3) }`

Explanation:

given f(x) = 3x^4

so let f(x) be y and to find inverse notation, we have to make x the subject

y = 3x^4

`(y)/(3)` = x^4

x =
`\sqrt[4]{(y)/(3) }`

so, inverse notation is:

`f(x)^(-1) = \sqrt[4]{(x)/(3) }`
