Given the function f(x) = 3|x – 21 +6, for what values of x is f(x) = 18?
ox=-2, x=8
x = -2, x = -6
x = -2, x = 6
x= -2, x=8

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:

the answer is b.)
