The graph of the function f(x) = (x – 4)(x + 1) is shown below. on a coordinate plane, a parabola opens up. it goes through (negative 1, 0), has a vertex at (1.75, negative 6.2), and goes through (4, 0). which statement about the function is true? the function is increasing for all real values of x where x < 0. the function is increasing for all real values of x where x < –1 and where x > 4. the function is decreasing for all real values of x where –1 < x < 4. the function is decreasing for all real values of x where x < 1.5.

The function is decreasing for all real values of x where x < 1.5.

Step-by-step explanation:

we have

This is a vertical parabola open upward

The vertex is a minimum

The vertex is the point (1.5,-6.25)

we know that

The function is decreasing in the interval ----> (-∞,1.5)  x < 1.5

That means----> the function is decreasing for all real values of x less than 1.5

The function is increasing in the interval ----> (1.5,∞)  x> 1.5

That means----> the function is increasing for all real values of x greater than 1.5

see the attached figure to better understand the problem

therefore

The statement that is true is

The function is decreasing for all real values of x where x < 1.5.

what are you doing do you need examples of variable questions?

step-by-step explanation:

5a-1=9               bring the one over the =

5a=10                     divide by your variable

a=2
