The function h(x) is quadratic and h(3) = h(–10) = 0. which could represent h(x)?

h(x) = x2 – 13x – 30

h(x) = x2 – 7x – 30

h(x) = 2x2 + 26x – 60

h(x) = 2x2 + 14x – 60

Step-by-step explanation:

Since, according to the question, h(x) is quadratic and at x=3, h(x)=0

And, at x=-10, h(x)=0 , That is, 3 and -10 are the roots of h(x).

According to the property of quadratic equation,If and   are the roots of a quadratic equation then the required quadratic equation is,

Therefore, If 3, -10 are the roots of the quadratic equation h(x).

Then,

⇒

⇒

Since, both h(x) and 2.h(x) (h(x) with multiplicity 2) must have the same roots.

Therefore, required quadratic function is

y/x=18

step-by-step explanation:

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
