Question

Decide if the function is an exponential function. If it is, state the initial value and the base.

y = - 7.3 ⋅ 2x

Exponential Function; base = - 14.6; initial value = 1
Exponential Function; base = x; initial value = - 7.3
Not an exponential function
Exponential Function; base = 2; initial value = - 7.3

Answer 1

The function written y = -7.3 (2^x) ineed is an exponential function.

The base is 2 (the exponent is x)

And the initial value is when x = 0 => -7.3(2^0) = -7.3(1) = -7.3.

Then, the answer is the fourth option of the list: Exponential function; base =2; initial value = -7.3
