IB Maths AA SL 2.2 Functions & inverses

IB Mathematics: analysis and approaches guide, first assessment 2021

Practise evaluating functions and inverses, stating domains and ranges, and linking algebraic definitions to graph information.

How this is tested

read values such as f(-3) from a graph or definition, keeping coordinates and function notation distinct
find f^-1(a) by solving f(x)=a, using logarithms or index laws when exponential functions are involved
state the domain of f^-1 or the transformed range from graph and endpoint behaviour

Consider the function f(x)=2 x+3 where $x \in \mathbb{R}$ .

Find

f(2);
