Answer

\[f\left( x \right)=a{{x}^{2}}+bx+c\]

Work Step by Step

We know that the quadratic equation is one of the form $f\left( x \right)=a{{x}^{2}}+bx+c$ where a, b and c are real numbers and a not equal to zero $\left( a\ne 0 \right)$. Let us consider the example: $f\left( x \right)={{x}^{2}}+2x-1$ is the quadratic function.
