explanation
since there are 2 x-intercepts, the lowest degree the function could possibly have is 2, so this could be the graph of a parabola
since our zeros are at x = 4 and x = -2, our factors are (x - 4) and (x + 2)
our equation so far is
(x - 4)(x + 2)
=
=
since the function is reflected across the x-axis, multiply the equation by -1
=
since the function has a vertical stretch of 3, multiply the equation by 3
=
