First step is to solve the quadratic function x

where a = 1, b = 5, c = 6.

The graph is facing upwards as a >0.

(x + 3) (x+ 2) = 0.

The solution is x = -2, -3 > the function has two x-intercepts.

The second step is to find the vertex of the function (-b/2a, f(-b/2a))

Vertex is (-5/2, -1/4)

First step is to solve the quadratic function 4x

where a = 4, b = 4, c = 1.

The graph is facing upwards as a >0.

We can find x-intercepts by plugging in y = 0 > (2x + 1)

The solution is x= -1/2

The second step is to find the vertex of the function (-b/2a, f(-b/2a))

Vertex is (-1/2, 0)
