If a=-3 and zeros are 4,-7
what would be the equation pf the parabola

-3x²-9x+84

Step-by-step explanation:

Let the zeros be r1 and R2

The equation of a parabola going through those two zeros is

y=a(x−r1)(x−r2)

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

b.-4 units

all you   do is count how many times you move
