m<1 = 20°

Step-by-step explanation:

m<L = m<Z = 70°

=> m<1 = 180° - 90° - m<Z

=> m<1 = 180° - 90° - 70°

=> m<1 = 20°

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

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
