Question 1

43017

The coordinates of the $x$-intercepts of a parabola are $(-2,0)$ and $(4,0)$. What is the equation of the axis of symmetry?

Answer

$x=1$

Worked Solution

The axis of symmetry lies on the mid point of $(-2,0)$ and $(4,0)$.
$$
\begin{aligned}
\therefore x_1&=\frac{-2+4}{2}\\
&=1\\
&\\
y_1&=\frac{0+0}{2}\\
&=0
\end{aligned}
$$

$\therefore$ The axis of symmetry is $x=1$.
