Find the equation of the axis of symmetry and the coordinates of the vertex of the graph of the function y = 2x2 + 4x –3

Axis of symmetry is x=-1.

The vertex of the graph is (-1,-5).

Step-by-step explanation:

If a quadratic function is , then the axis of symmetry is

The given equation is

Here,

The axis of symmetry is

Substitute x=-1 in the given equation to find the y-coordinate of the vertex.

Therefore, the vertex of the graph is (-1,-5).

1/3

step-by-step explanation:

to find this, you can divide 12 by 4 which is 3 or you can multiply 4 until you reach 12 (4x3=12). both should give you 3, meaning theres three times less bananas than there are oranges.
