Question

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

Answer 1

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

Answer 2

Answer:no, the function may be rewritten so that the constant multiplier is 4 -2, a positive number raised to a negative exponent.
