(a)[2]
Complete the table.
(b)[5]
On the grid, draw the graph of $y=f(x)$ for $-10\le x\le -1.6$ and $1.6\le x\le 10$.
(c)[2]
Using your graph, solve the equation $f(x)=11$.
(d)[2]
Find the possible values of $k$.
(e)[1]
Write down the co-ordinates of the other point on the graph of $y=f(x)$ where the gradient is $-4$.
(f(i))[2]
Show that $p=-1$ and $q=-20$.
(f(ii))[2]
Using the grid opposite, sketch the graph of $y=x^2$ for $-4\le x\le 4$.
(f(iii))[1]
