Which description is correct for the x-intercept(s) of Function A and Function B?

Function A:

x g(x)

−4 −3

3 0

0 −2

2 −1

1 0

Function B: f(x)=|x|−2

Both functions have the same x-intercept(s).

Function A has two x-intercepts.

Function B has one x-intercept.

Both functions have the same number of x-intercepts.

Function B has two x-intercepts.

Function A has one x-intercept.

Function A has two x intercepts since the points (3, 0) and (1,0) are on the graph

To find out the number of x intercepts that B has

l x l - 2 = 0

l x l = 2

Two values of x satify this x = 2 and x = 2

So....B has two x intercepts

So

Both functions have the same number of x-intercepts.

[ But not the SAME x intercepts ] !!!!
