Find the function with x-intercepts (-2, 0) and (4, 0), which also goes through the point (3, 10).

Option D:  is the function

Explanation: Let the general form of quadratic equation be  The function passes through the intercepts  and  and also passes though the point  Substituting the points ,  and  in the equation , we get,   (1)  (2)     (3) Subtracting (1) and (2), we get,   (4) Subtracting (2) and (3), we get,   (5) Multiplying equation (4) by 5 and equation (5) by 4, to cancel the term b when adding, we get, Thus, the value of a is  Substituting  in equation (4), we get, Thus, the value of b is  Now, substituting the value of a and b in equation (1), we have, Thus, the value of c is  Now, substituting the value of a,b and c in the general formula , we get, Taking out the common term as -2 we get, Factoring , we get, Thus, the function is  

50- 250 is correct i did that one too

step-by-step explanation:

i believe that the answer is

b. y-1=-2(x-4)

hope this !
