What is the sum or difference? a. 5x4 + 4x4 b. 12x5y − 9x5y a. a. 9x4 b. 3x5y b. a. 20x16 b. −108x25y2 c. a. 9x8 b. 3x10y d. a. 9x16 b. 3x25y2

A.a. 9x^4 b. 3x^5y

Step-by-step explanation:

a. 5x^4 + 4x^4

Since these are to the same power, they are like terms and we can add them

9x^4

b. 12x^5y − 9x^5y

Since these are to the same power, they are like terms and we can subtract them.

3x^5y

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
