Question

In which direction must the graph of f(x) = x2 be shifted to produce the graph of g(x) = (x + 7)2?

Answer 1

Now, consider the equation
y=a(x-h)^2+k
Recognize it? It's vertex form!

Answer 2

left

Answer 3

Now, for f(x), (h,k) is (0,0), because f(x)=1(x-0)^2+0

Answer 4

g(x)=1(x+7)^2

Answer 5

the vertex of g(x) is (-7,0)

Answer 6

Because the vertex of g(x) is to the left of the vertex of f(x), we must shift f(x) left.

Answer 7

ok,, i'll work this out on my sheet of paper so i can have a definate understanding,, it'll only take a couple of minutes !

Answer 8

RIGHT AGAIN !!

Answer 9

Does it all make sense to you?
