What is the equation of a parabola that intersects the x-axis at points (-1, 0) and (3, 0)?

A. y = x2 – 2x – 3

B. y = x2 + 3x + 2

C. y = x2 – 3x + 2

D. y = x2 + 2x – 3

Step-by-step explanation:

The given points are zero's or roots of the function.

We can put the equation as:

This is option A

a

Step-by-step explanation:

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
