HELP ME PLEASE Determine if the function f is an exponential function. If so, identify the base. If not, why not? f(x) = 2x + 4

A) This is a polynomial.

B) This is not an exponential function because the variable is in the exponent position.

C) The base is x + 4.

D) The base is 2.

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.

Idon’t know i’m in the same boat
