2.9 Exponential and Logarithmic functions

Key ideas

• The parameters in a function or equation correspond to geometrical features of a graph and can represent physical quantities in spatial dimensions.

• Moving between different forms to represent functions allows for deeper understanding and provides different approaches to problem solving.

• Our spatial frame of reference affects the visible part of a function and by changing this “window” can show more or less of the function to best suit our needs.

• I can use transformations and other techniques, including technology, to graph exponential and logarithmic functions

• I can explain how exponential and logarithmic functions are inverses of each other.
