Answer:

C

Step-by-step explanation:

So we have the function:

h(x)=e^{2x}

To find the inverse, switch h(x) and x, change h(x) to h⁻¹(x), and solve for it. Thus: "

x=e^{2h^{-1}(x)}

So, take the natural log (log to base e) of both sides:

\ln(x)=\ln(e^{2h^{-1}(x)})

The right side will cancel:

\ln(x)=2h^{-1}(x)

Divide both sides by 2:

h^{-1}(x)=\frac{1}{2}\ln(x)

And we're done!

Our answer is C

Note:

\ln(x)=\log_ex
