Consider the quadratic function that has x-intercepts of -1 and -7 and passes through the point (-2, -20). What is the value of a in the factored form of this function? 0 1 02 O 3 O 4​

answer: 4 (:

step-by-step explanation:

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
