Question

Given a = -1, h = 4, and k = -2, what is the equation of the graph if the parent function is y=√x

Answer 1

Use the equation

\[y=a \sqrt{x-h}+k\]

Then simply plug in the numbers that they gave you.

Answer 2

Most textbooks show that for any function y=f(x), the transformed function is y=a f(x-h) + k

So if \[f(x)=\sqrt{x}\], the transformed form would be \[-\sqrt{x-4}-2\]
