Only one direct question exists, so keep the focus narrow: read the graph of f(x) and state every interval where the curve is below the line.
Figure 2
Figure 2 shows a sketch of the straight line l and the curve C.
Given that l cuts the y-axis at -12 and cuts the x-axis at 4, as shown in Figure 2,
Given that C
- has equation y=f(x) where f(x) is a quadratic expression
- has a minimum point at (7,-18)
- cuts the x-axis at 4 and at k, where k is a constant
The region R is shown shaded in Figure 2.
Use inequalities to define R.
