what is the parent function ?

Question

quadratic parent function that reflects across the x axis and is horizontally stretched by a factor of 6 and iis horizontally shifted 8 to the left vertically compress by a factor of 3/4 and is vertically shifted 9 down

Answer 1

y = x²                                reflects across x axis

y = (x/6)²                          horizontally stretch by 6

y = ((x + 8)/6)²                 shifted left 8

y = (3/4)((x + 8)/6)²         vertical compression of 3/4

y = (3/4)((x + 8)/6)² - 9    shifted down 9

 

Note: 

An alternative function is y = -x².
