?
positive or negative
greater than 1 or less than 1
We can tell whether an exponential function is increasing or decreasing by whether is
?
positive or negative
greater than 1 or less than 1
If a linear function has slope 1.5, each time we increase the input by 1 unit, how do we find the new function value from the old one?
?
Add 1.5
Multiply by 1.5
If an exponential function has growth factor 1.5, each time we increase the input by 1 unit, how do we find the new function value from the old one?
?
Add 1.5
Multiply by 1.5
