The graph of g(x) is the graph of f(x) = x^2 shifted 4 units left, vertically streched by a factor of 3, then shifted 5 units up. What is the function rule for g(x)?

If you could explain the steps in how you got the answer that would be so great. :P

Respuesta :

I think it would be (x)=2x2
f(x) = x^2

4 unit shift to left:  (x^2 + 4) 

vertical stretch factor of 3:  3 ( x^2 + 4)

upward shift of 5:  3(x^2 + 4) + 5

g(x) = 3(x^2 + 4) + 5
