Find the equation for the quadratic function whose x-intercepts are -1 and 3with the leading coefficient is 2

y = 2x² + 8x + 6

Step-by-step explanation:

given x = - 1 and x = - 3 are x- intercepts then

(x + 1) and (x + 3) are factors and

y = a(x + 1)(x + 3)

given a = 2, then

y = 2(x² + 4x + 3)

  = 2x² + 8x + 6

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)

the answer is 21%.
