Ive got quite a few questions that i need help with. First,

The graph of F(x), shown below, has the same shape as the graph of G(x)=3x^2, but it is shifted down 2 units. What is the equation?
A) F(x)=3x^2+2
B)F(x)=3(x-2)^2
C) F(x)=3x^2-2
D) F(x)=3(x+2)^2
I think it's C

welshfella · Answer

f(x) ---> f(x) - 2   is a shift down 2 units

welshfella · Answer

youe are right

anonymous · Answer

I know that a shift right is x-x a shift left is x+x and up is x+x while down is x-x

welshfella · Answer

more accurately
f(x) - a  and f(x) + a are shifts a of the whole graph down and up

welshfella · Answer

shifts left and right are f(x+a) and f(x -a)
