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 number of x-intercepts.

  • Function A has two x-intercepts.
    Function B has one x-intercept.

  • Function B has two x-intercepts.
    Function A has one x-intercept.

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

Thanks so much for your help!

Function A has two x intercepts, (3,0)  and (1,0)

 

Function B,  y   = l x l - 2 , also has  two x intercepts  = (2,0)  and (-2, 0 )

 

So.....the have the same number of x intercepts......{ but not the same x intercepts }

 

 

cool cool cool
