In the following exercise, find the coordinates of the vertex for the parabola defined by the given quadratic function.
f(x) = 4x2 + 16x + 1
The vertex is
(Type an ordered pair.)

The vertex is the point at which the parabola or quadratic equation opens up or down. To calculate the parabola, we must use the formula: -b/2a = x; x = -16/2(4) x = -2
Substitute -2 in where you see x appear and do the arithmetic to find that y = -15. Therefore, the vertex coordinates are (-2,-15).

The second step on the test was the move he was supposed to
