I need your help! I am far behind in this class and I need to submit two assignments tonight!

PLEASE SOMEONE HELP ME

Any function f(x) may be translated to the \(right\) by h units and up k units by g(x)=f(x-h)+k In your particular case, k=0. For example, to translate f(x)=x^3+x 3 units to the \(left\), we have g(x) =f(x-(-3)) =f(x+3) =(x+3)^3+(x+3) =x^3+3x^2+9x+27 + (x+3) =x^3+3x^2+10x+30 In your case, g(x)=f(x+4), figure out the translation that makes this happen.
B? @mathmate

Others might be slightly more inclined to help you if you'd express your exponentiation properly: Correct: "y = x^2 can be transformed to the graph of the given equation. y = (x+4)^2
im correct?
Rule: If you are given y=f(x) and are asked to graph it, then the function f(x-a) has a graph that is identical to that of f(x), BUT has been shifted "a" units to the right (assuming that "a" is positive. Can you use this fact to answer the original question?
yes
Can't tell you whether you're correct or not; you haven't posted a response (at least not one that I can see).
I said B lol way up in the comments somewhere
"y = x^2 can be transformed to the graph of the given equation. y = (x+4)^2" Please draw the graph of y=x^2. Then, using the info I've shared with you, decide how the graph of y = (x+4)^2 will differ from that of y=x^2.
B is not correct. We'll discuss why, later. For now, please read the Rule I've shared with you, above.

x+4=0 x=-4 so 4 units left.
thank you
x-5=0 if x=5 , 5 units right
y = x2 + 8
@sshayer what about that one?
when x=0,y=8 so 8 units up
if y=x^2-7 when x=0 y=-7 so 7 units down
y = (x+9)2-3
@kellyspeakslouder More than one helper has shown you the way to figure out the answer. The idea is once you have understood how translation works, you can work out the problem by yourself and be proud about it. Otherwise, you'd need "help" whenever this kind of problems pop up.
