CAIE IGCSE Mathematics Extended Plotting and Solving Function Graphs

Cambridge IGCSE Mathematics 0580 syllabus for exams in 2028, 2029 and 20302028–2030

Practise calculating and plotting function values, drawing a smooth curve and using a suitable additional line to obtain graphical roots.

How this is tested

complete missing table entries by evaluating the printed function at each stated x-value
plot points within the grid tolerance and connect them with one continuous smooth curve
draw the rearranged auxiliary line and record all x-coordinates where it intersects the curve

[Maximum number: 4]

The table shows some values for $y=x^{3}-2 x+3$ .
Where appropriate, values of y are given correct to 2 decimal places.

Draw the graph of $y=x^{3}-2 x+3$ for $-2 \leqslant x \leqslant 2$ .
