Answer:

g(x) = 12 {e}^{ - x - 7}

Step-by-step explanation:

The parent function is

g(x) = e {}^{x}

First it is asked to reflect over the y axis so using the rule

g(x) = g( - x)

Our function looks like

g(x) = e {}^{ - x}

Then we are asked to shift the equation to the right 7. When shifting to the right or move the x axis, instead of adding 7 we would want to subtract 7 since the x axis is the independent variable and we must respect the y axis which is the dependent so using the rule

g(x) = g(x - h)

When subtracting a 7 it looks like now

where h is the number we move . Now we are asked to apply a vertical stretch of 12. Since vertical stretch refers to the y axis, we are just going to multiply the function by 12 using the rule

g(x) = a \times g(x)

where a is the vertical stretch. So now it would look like

g(x) = 12 {e}^{ - x - 7}
