Choose the correct option.
Let f(x) = x³ be a function with domain {0, 1, 2, 3}. Then domain of f⁻¹ is:
Let $f(x) = x^3$ be a function with domain $\{0, 1, 2, 3\}$. Then domain of $f^{-1}$ is:
- (a)$\{3, 2, 1, 0\}$
- (b)$\{0, -1, -2, -3\}$
- (c)$\{0, 1, 8, 27\}$
- (d)$\{0, -1, -8, -27\}$
Answer
Answer
Correct option: (c)
Answer: (c) $\{0, 1, 8, 27\}$
The domain of $f^{-1}$ is the range of $f$.
$f(0)=0,\ f(1)=1,\ f(2)=8,\ f(3)=27$.
