Question

If the points (0, 0), (-1, 1), and (-2, 2) lie on the graph of function h, then which of the following rules could represent the function?


h(x) = x2
h(x) = |x|
h(x) = -2x

Answer 1

See that the y-coordinates are the negative of the x-coordinates, so the function would be something that converts negative values to positive. Now, which function do you think does it?

Answer 2

thanks

Answer 3

It's not -2x...

Answer 4

Sorry, you are right! it is the absolute value of x. |x|

Answer 5

h(x) = |x|
