\[f(x) = (x + 2)^2 - 1\]
\[x = - rac{b}{2a} = - rac{3}{4}\]
\[(x + 2)(x + 3) = 0\]
\[f(x) = ax^2 + bx + c\]
A quadratic function is a polynomial function of degree two, which means the highest power of the variable (usually x) is two. The general form of a quadratic function is:
where a, b, and c are constants, and a ≠ 0.
