Question

Amber is trying to solve 3x^2-4x=0 using a graphical method. She therefore starts by drawing the graph of y=3x^2 on a grid she now intends to complete her method by drawing a straight line graph in the same grid. complete Ambrrs method to solve 3x^2-4x=0

Answer 1

Draw a graph of y=4x, and the x-coordinates of the points of intersection, if I’m not mistaken, are the answers.

Answer 2

You can rewrite the equation as

$3x^2-4x=0 \iff 3x^2=4x$

So, you draw the graph of $y=3x^2$ (the parabola), and then the graph of $y=4x$ (the line), and see where they intersect.
