Select from the drop-down menu to correctly complete the sentence.

The vertex represents

The vertex represent the minimum amount of profit

Step-by-step explanation:

Plot the function to better understand the problem

Let

x ----> the number of users in thousands

y ---> the Monthly profit in thousands

using a graphing tool

see the attached figure

we have a vertical parabola open upward

The vertex represent a minimum

In the context of this problem

The vertex represent the minimum amount of profit

In this problem the vertex is the point (0.4,-4)

0.4 represent -----> 0.4(1,000)=400 users

-4=-4(1,000)=-$4,000 (profit negative)

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true
