Exponential Functions
- Know the graph of the exponential function and its properties.
- If the base is greater than 1, the function is exponential growth. If it is between 0 and 1, it is exponential decay.
- Solve exponential equations with the same base by equating the exponents.
- Solve exponential inequalities with the same base by applying the same inequality to the exponents.

Correction to Example III: The solution, x = 8/38 reduces to 4/19, not 2/19

Dr carleen must the base be the same in all exponential equation are is this only when your working with certain exponential fuction

In the slide labeled 'Properties', at about 12:50, you mention f(x) is 'one-to'one' and give the reason that it passes the vertical line test. For a function to be 'one-to-one' it must pass the horizontal line test.

FOr some reason it will not play. Question is IF i have a expo equations of y=-5^x same as y=(-1)(5^x) ? Also is it decay or growth since it is not above the x axis?

If there is no variable in the exponent, will it just be a power function instead? Does it have to have variable for it to be exponential? Thanks!!
