Key concepts
3 concepts
- 1
The general form of an exponential function is y = a * b^x, where 'a' represents the starting value or y-intercept and 'b' represents the growth rate.
- 2
To write an exponential function from a graph, first create a table using points from the graph, then find the growth rate and starting value.
- 3
The growth rate ('b') can be found by dividing the 'new' y-value by the 'old' y-value, using the formula new/old, and the y-intercept is the value of 'y' when x is zero.
