Let $f(x)=x^3$ be a function with domain $\{0,1,2,3\}$ then domain of $f^{-1}$ is :
Answer & explanation
Correct answer: option 3
f(x) = x3
domain = {0, 1, 2, 3}
so range = ?
checking for each value of domain
f(0) = 03 = 0
f(1) = 13 = 1
f(2) = 23 = 8
f(3) = 33 = 27
range = {0, 1, 8, 27}
for f(x)
for f-1(x)
Domain (f-1(x)) = {0, 1, 8, 27}
