Determine whether or not the given function is an exponential function.
-$y = x ^ { 7 } + 9 x$
A) exponential
B) not exponential

Question

Quizplus · Accepted Answer

An exponential function is of the form $f(x) = a \cdot b^x$, where $a$ and $b$ are constants, and $b$ is positive. The given function $y = x^7 + 9x$ is a polynomial, not an exponential function, because the variable $x$ is in the exponent in an exponential function, whereas here it is the base being raised to a constant power.

Determine Whether or Not the Given Function Is an Exponential y=x7+9xy = x ^ { 7 } + 9 xy=x7+9x
