Decide if the function is an exponential function. If it is, state the initial value and the base.
-$$\mathrm { y } = 3.8 ^ { \mathrm { x } }$$
A) Not an exponential function
B) Exponential Function; base $= 3.8$; initial value $= 0$
C) Exponential Function; base $= 3.8$; initial value $= 1$
D) Exponential Function; base $= x$; initial value $= 3.8$

Question

Quizplus · Accepted Answer

The given function $y = 3.8^x$ is an exponential function because the variable $x$ is in the exponent. The initial value is the output when $x = 0$, which is $3.8^0 = 1$, and the base of the exponential function is $3.8$.

Decide If the Function Is an Exponential Function y=3.8x\mathrm { y } = 3.8 ^ { \mathrm { x } }y=3.8x
