Answer:
[tex]f(x)^{-1} = \sqrt[4]{\frac{x}{3} }[/tex]
Step-by-step 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
[tex]\frac{y}{3}[/tex] = x^4
x = [tex]\sqrt[4]{\frac{y}{3} }[/tex]
so, inverse notation is:
[tex]f(x)^{-1} = \sqrt[4]{\frac{x}{3} }[/tex]
