Drawing Graphs
Starter
Use a calculator to find the values of the given expressions at the given values:

a) x + 2x - 3 at x = -3, -2, -1, 0, 1, 2, 3

b) x - x + 2x - 1 at x = -3, -2, -1, 0, 1, 2, 3

c) at x = -3, -2, -1, 0, 1, 2, 3

d) sin x at x = -30, -15, 0, 15, 30, 45, 60, 75, 90, 105, 120
Example
f(x) = sin x
