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

    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
