find the value of x. if necessary, write your answer in simplest radical form

Step-by-step explanation:

a^2+b^2=c^2

8^2+x^2=12^2

64+x^2=144

x^2=80

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
