Is 3/x a polynomial expression

Step-by-step explanation:

3/x

=3×1/x

=3×x^-1

It isn't a polynomial because the index of x is -1 which is a negative integer.

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:

i believe that the answer is

b. y-1=-2(x-4)

hope this !
