Question

3. Which of the following quadratic functions has a maximum point?

Answer 1

The general form of a quadratic equation is given by the expression:

`ax^2+bx+c=0`

A quadratic equation having a maximum value or point is one that has its value of a to be lesser than zero

(a < 0). Such a graph opens downwards

Therefore, any quadratic equation that has the a-value to be lesser than zero has a maximum point

Mathematically expressed as:

`\begin{gathered} y=-x^2 \\ \Rightarrow a=-1 \end{gathered}`
