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

Option B.

Step-by-step explanation:

The given function is

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

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.

answer: 21$

step-by-step explanation:

$42 / $14 = 3   (ratio 3: 1)

$7 x 3 = $21
