Now the amount of Job left is

Let t be the amount of time Stephen takes to do the remaining job of

                        hours

Now let's convert hours into minutes as :

minutes

Therefore, it will take 140 minutes to Stephen to finish the job by himself.

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

step-by-step explanation:

341

step-by-step explanation:
