The graph of the function f(x) = (x + 2)(x - 4) is shown. A. all real values of x where x < -2

B. all real values of x where -2
C. all real values of x where 1 D. all real values of x where x <0

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

last one.

step-by-step explanation:

last one.

generally speaking, the others follow some sort of pattern that correlates to either linear (looks like a straight line) or sinusoidal (looks like an s).

the last one is just a random cloud of points that doesn't correlate to any particular known order.

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
