Question

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

Answer 1

Given

The function,

$f(x) = 2 \times {3}^{x}$

To find:

The y-intercept.

Explanation:

It is given that,

$f(x) = 2 \times {3}^{x}$

Then, set x=0.

That implies,

$\begin{gathered} f(0)=2\times3^0 \\ =2\times1 \\ =2 \end{gathered}$

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