Gap-fill
Ask the student a question, and give any hints about how they should answer this part.
(i) {plotgraph(1,x11,x12,-1,10,a1,b1,0)}
This is the graph of the function f(x)={{a1}x+{b1}}.
Which integral corresponds to the area of the shaded region?
(ii) {plotgraph(3,x31,x32,-3,7,a3,b3,0)}
This curve has equation y={x2−{a3+b3}x+{a3b3}}.
Which of these integrals does not give the area of the red region?
Which of these calculates the total area of the two shaded regions?
Use this tab to check that this question works as expected.
