At the beginging of the course we had explored the linear function family which was defined by the equation y= mx+ b we have studied the roles of parameters m and b. What we found was that no matter the numbers we used to preplace either m or b our graphs had straight lines.
In this section we will explore a different equation. y= a x b^x ( y equals a times b to the power of x) Parameter A- is the coefficient Parameter B- is the base in this unit we will explore the roles of parameter a and b
When parameter B is positive the line (curve) on the graph will INCREASE When parameter B is negative the line (curve) on the graph will DECREASE When parameter B is equal to 1 the line (curve) on the graph will STAY STRAIGHT
When parameter A is positve the line (curve) on the graph will INCREASE When parameter A is positive the line (curve) on the graphh will DECREASE When parameter A is equal to 1 the line (curve) on the graph will STAY STRAIGHT
If parameter B is negative the line will disapear.
