Question
Identify the exponent and the coefficient for each power function.The surface area of a sphere of radius $r$ is $S=4 \pi r^{2}$.
Step 1
The power function is a function of the form $f(x) = kx^p$, where $k$ is a constant, $x$ is the variable, and $p$ is the exponent. In our case, the power function is $S = 4\pi r^2$. Show more…
