The graph of the function fx x 2x 4 is shown A all real values of x where x lt 2 B all real values of x where 2 C all real values of x where 1 D all real values class=

Respuesta :

Answer:

B)   All real values of 'x' where -2 < x< 4

Step-by-step explanation:

Explanation:-

Given function f(x) = (x +2 ) ( x-4)

                  (x+2)(x-4) =0

          ⇒  x +2 =0 and x-4=0

          ⇒  x =-2   and x=4

From graph

       Given parabola lies between the x=-2 and x =4

∴ All real values of 'x' lies between x=-2 and x =4

 All real values of 'x' lies -2 < x< 4
