Is the function ƒ(x) = (4)x – 2 an exponential function? If so, identify the base. If not, why not?

What is on the exponent?

nyababie · Answer

no it's not an exponential equation in which f(x)is not qualified to an exponential number. no number from 1 - 20 can be used and get subtracted by 2 to give a square number. 
eg-
4×2-2≠ square number

imqwerty · Answer

if you have a constant raised to the power of the argument in your function then it's an exponential function
and your constant should be any positive number other than $1$

I'd rather see the question as it was originally posted.

If has the form  $f(x) = a^{x+b}$ where $x + b$ is the exponent, then it is an exponential function

Hero · Answer

And if so, then $a$ is the base

Hero · Answer

If it does not have that form, then it is probably something else

I practically gave you the answer. So which one is correct?

eviant · Answer

I know it is an exponential function
I'm just having trouble identifying the base
