Find the y-intercept and the axis of symmetry of f(x)=ax2+2ax+3.

We see that:

The axis of symmetry is defined by this formula:

And replacing we got:

Thn the axis of symmetry would be X=-1

Step-by-step explanation:

For this case we have the following function:

If we compare this function with the general expression of a quadratic formula given by:

We see that:

The axis of symmetry is defined by this formula:

And replacing we got:

Thn the axis of symmetry would be X=-1
