Question

Do you know how to do this?

Answer 1

`y=4(3)^(x)`

Explanation:

Let the exponential function is,

f(x) = (b)ˣ

If this function has the base (b) = 3, function will be.

f(x) = (3)ˣ

If this function is transformed by a vertical stretch by a factor of 4,

New function will be,

g(x) = 4(3)ˣ

If the function 'g' is reflected across y-axis, new function will be,

h(x) = g(-x)

h(x) =
`4(3)^(x)`

Therefore, equation of the function will be,

`y=4(3)^(x)`
