Question

PLEASE HELP!!!

Which of the following functions represents the following graph?

a) f(x) = sqrt x+2-1
b) f(x) = (x + 2)2 - 1
c) f(x) = -1/x+2
d) f(x) = (x + 2)3 - 1

Answer 1

Well that general shape for a graph [ie a U shape] is that of an x^2 function

if it was an upsidedown U it would be a '-x^2' function

So, looking at the options you are given, can you identify which of the functions has an 'x^2' component in it?

I could just tell you the answer, but I feel it's better for you to understand why it is the one it is, I hope that's okay :)

Answer 2

and also take into account, looking a the graph, that it has been translated from the origin

Answer 3

So have a look at the different options and let me know which you think it is :)
