Practice problem
If f(x)=(2x)xf(x) = (2^x)^xf(x)=(2x)x on the domain x∈[1,∞),x \in [1, \infty),x∈[1,∞), what is the inverse f−1(x)?f^{-1}(x)?f−1(x)?
2log2(x)2\log_2(x)2log2(x)
log2(x)\sqrt{\log_2(x)}log2(x)
−log2(x)-\sqrt{\log_2(x)}−log2(x)
12log2(x)\frac{1}{2}\log_2(x)21log2(x)
The inverse does not exist on the given domain.
Type a concept, like “slope” or “photosynthesis”.
