If a polynomial function f(x) has roots –9 and 7 – i, what must be a factor of f(x)? (x – (7 + i)) (x – (–7 – i)) (x + (7 + i)) (x + (7 – i))

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
