Simplify the product.
4x (2x^3 - 7x^2 + x)

a) 8x^4 - 28x^3 + 4x^2
b) 16x^3 - 7x^2 + x
c) 8x^4 - 7x^2 + x
d) 16x^4 - 3x^3 + 4x^2

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
