Which is the completly factored form of 3x2-12x-15?

(3x-15)(x+1)

Step-by-step explanation:

Given an expression in the form ax²+bx+c, where a,b and c are constants,  we can factor it by first finding the two numbers that when multiplied equal to ac and when added equal to b

The expression 3x²-12x-15 can be factored as follows:

The two numbers that can be added to give 3×(-15) and when added result to -12 are -15 and 3.

Thus, 3x²+3x-15x-15

3x(x+1)-15(x+1)

The simplified form becomes: (3x-15)(x+1)

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 c.
