What is a linear function?
Linear functions are those which graph a straight line. Learn how to work with them here: Linear Models
What is a function?
Functions have specific properties which distinguish them from relations. Introducing Functions
What is some key features of functions?
Functions have specific features such as stationary points, asymptotes and intercepts that we need to bear in mind. In an exam, you may also be asked to draw or sketch them. Key Features of Functions and Graphing
What are the features of quadratic models?
Quadratic graphs and equations have many interesting features, such as turning points and symmetry which make them very useful to solve real life problems Quadratic Models
What are the key features of trigonometric models?
Trigonometric models are used to model all sorts of real life situations such as tides, length of days, and even ferris wheels. Trigonometric Models
What are exponential models for?
Exponential models are used to model many types of natural phenomena, such as population, spread of disease, and interest rates Exponential Models
Commonly seen in the form y = f(x) = mx + c where m represents the gradient/rate of change of the function and c is the y-intercept, where x = 0. These models are a fundamental bit of algebra that come up again and again. they are also fairly...
Quadratic functions are in the form ax2 + bx + c, and have fascinated mathematicians for centuries. They have some fundamental properties that will explored in this unit. Probably the best known example of quadratic models are for projectiles....
The exponential function is set apart from other families of functions because of the fundamental impact of having the variable in the exponent. It stops being a multiplier and starts being more 'powerful' (forgive the bad joke). These functions...
