Mathematics for IGCSE & O level - Sketching Curves (Section 5 - No. 20)

If the function is \(y=x^3+x^2-6x\), how can you find where this graph crosses the x-axis?

Set y = 0 and solve for x

Set x = 0 and solve for y

Find the area under the curve

Find the turning points

x-intercepts are found by setting y=0 and solving for x
