G1 Graphs of functions

 

Content

Additional information

G1.1

sketching and plotting curves defined by simple equations

knowing the shapes of the graphs of linear, quadratic, cubic and exponential functions will be expected

G2 Intersection points

 

Content

Additional information

G2.1

plotting and interpreting graphs (including exponential graphs) in real contexts, to find approximate solutions to problems

including understanding the potential problems of extrapolation

G2.2

interpreting the solutions of equations as the intersection points of graphs and vice versa
