Question

Convert the quadratic function y = x2 + 8x + 20 to vertex form.

Answer 1

Given data;

`y=x^2+8x+20`

To convert it to vertex form.

The vertex of the above function is, (-4,4).

the general equation is,

`y=a(x-h)^2+k`

Thus, the vertex form of the quadratic equaion is,

`y=(x+4)^2+4`

The answer is option a.
