Question

In which type of relationship will the graph never pass through the coordinate pair (0,0)

1.linear
2.quadratic
3.inverse
4.direct

Answer 1

None of the above. Examples for each:
1) y=x 2) y=x^2 3) y=-x 4) y=x is a direct relationship as well as linear

Answer 2

hhmmm -isnt y = 1/x an inverse relationship?

Answer 3

It is, but he is asking for a class of functions for which (0,0) is never a solution

Answer 4

Inverse relationship means that as x increases, f(x) decreases. So an example of an inverse relationship for which x=0 is a solution, is f(x)=-x.
