Math Transformations Question?
I need help solving this:
The graph of y1 = 1/x^2
The graph of y2 = 1/(x^2+6x+9)
Describe how y2 is a transformation of y1.

factor the bottom of the second function
so now you have
y2 = 1/(x+3)²
when compared to the first one the (x+3) is there instead of just an x
there is a horizontal shift ( translation) of 3 units to the left ( opposite --> x+3 = 3 left ) when compared to the first equation
