Sketch y= -(1/4) (2)^(x-4)+5 I know that the basic equation is y=2^x so is the graph translated 4 units right, vertically stretched by a factor of (1/4), reflected on the x-axis and translated up 5?

**check math question**

Thank you!

**check math question**

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?
