Answer:
$ 404.17 every month
Step-by-step explanation:
$19,700/2 =$9,850
$9,850-$5,000= $4,850
$4,850/12 = $404.1666666666667
rounds to $ 404.17
So since the vertex falls onto the axis of symmetry, we can just solve for that to get the x-coordinate of both equations. The equation for the axis of symmetry is , with b = x coefficient and a = x^2 coefficient. Our equations can be solved as such:
y = 2x^2 − 4x + 12:
y = 4x^2 + 8x + 3:
In short, the vertex x-coordinate's of y = 2x^2 − 4x + 12 is 1 while the vertex's x-coordinate of y = 4x^2 + 8x + 3 is -1.
