HELP

is the function ƒ(x) = x8 an exponential function? If so, identify the base. If not, why not?


No, the base is not a real number and the exponent is not variable.

No, the base is not a positive real number not equal to 1 and the exponent is not variable.

yes, base = 8

yes, base = x

Answer 1

no, the base is not a real number and the exponent is not variable. Exponential functions are when there is a number raised to a power.

Answer 2

Option B.

Explanation:

The given function is

`f(x)=x^8`

Here, base is x and exponent is 8.

We need o check weather the given function is an exponential function or not.

The general form of an exponential function is

`f(x)=a^x`

where, a is base, a > 0, and a ≠ 1.

In the given function the base is not a positive real number not equal to 1 and the exponent is not variable. So, the given function is not an exponential function.

Therefore, the correct option is B.
