Graphs of functions
What this topic asks you to be able to do
- Construct a table of values for each function of the form axn (and sums of no more than three such terms) or abx + c, and draw, recognise and interpret its graph, where n = –2, –1, 2 1 − , 0, 2 1 , 1, 2, 3; a and c are rational; and b is a positive integer.
- Solve the related equations from their graphs, including finding the roots graphically and interpreting them.
- Draw and make sense of graphs that model situations of exponential growth and decay.
- Estimate the gradient of a curve by drawing a tangent to it.
