Question

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

Answer 1

So you have a parent function. The h,k values will shift the graph of this function up/down and left/right according to the sign of h,k and how large h,k are. Do you remember the rules for these? I forgot them.

Answer 2

Use this equation, and plug in the values you're given (a = -1, h = 4, and k = -2) \[\Large y = a \sqrt{x- h}+k\]
