Matrices C and D are shown below.
What values of a and b will make the equation CD = I true?

The answer is A

Step-by-step explanation:

You should set "I" as

1 0 0

0 1 0

0 0 1

then replace "a" to 0.5 and "b" to 0.1

then finally you multiply matrice C and D

If your answer is

1 0 0

0 1 0

0 0 1

then the answer will be A

the correct answer is 5

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
