Given y=2^x

Predict the equation for the graph that has been reflected in the y-axis, given a vertical stretch by a factor of 5, translated 2 units right and 5 units down.

I have:

y= -5 (2) ^ (x-2) - 5

Is this correct?

correct

Thank you!

actually that's wrong..
that will give you a reflection in the x-axis if you want a reflection in the y-axis you have to make the x in the exponent negitive.

i believe the answer is
y=5*2^((-x)-2)-5
