Exploring Functions Involving Fractional and Negative Powers of x C2
In this DfE Standards Unit resource, students find the stationary points of a function and determine their nature and solve appropriate equations in order to find the intercepts of a
function. Students are encouraged to connect the mathematical properties of a function and relate them to the graph. Before starting the activity students should understand that f ′(x) = 0 finds stationary points and f ″(x) determines their nature and be familiar with fractional and negative indices (AS and A2 level)
