What is the y intercept of the following f(x) = 2 * {3}^(x)

Question

What is the y intercept of the following
`f(x) = 2 * {3}^(x)`

Answer 1

Given

The function,

`f(x) = 2 * {3}^(x)`

To find:

The y-intercept.

Step-by-step explanation:

It is given that,

`f(x) = 2 * {3}^(x)`

Then, set x=0.

That implies,

`\begin{gathered} f(0)=2*3^0 \\ =2*1 \\ =2 \end{gathered}`

Hence, the y-intercept is at (0,2).
