Question
A function of the form $f(x)=x^{r},$ where $r$ is a constant, is a power function. Discuss the difference between an exponential function and a power function.
Step 1
A power function is a function of the form $f(x) = x^{r}$, where $r$ is a constant. This means that the variable, in this case $x$, is the base and the exponent is a constant. Show more…
