Exponential Functions Corbettmaths. In working with these problems it is most important to remember that y = logb x and x = by are equivalent statements. Practice graphing exponential functions on this quiz and worksheet.

The corbettmaths practice questions on composite functions and inverse functions A) exponential growth b) exponential decay c) linear d) none of the above which of the following functions shows an initial amount of \$15 and an increase of 35% each year? \color{red}e^{x} has special properties, most notable being that the gradient of \color{red}e^{x} is \color{red}e^{x}.

### 1 Exponentials Ef We Have Already Met Exponential Functions In The Notes On Functions And Graphs.

If log9 x = 1 2 then x = 912 x = p 9 x = 3 For igcse further maths, also covers piecewise functions and domain/range. A level maths revision tutorial video.for the full list of videos and more revision resources visit www.mathsgenie.co.uk.

### Originally Used For A Gcse Higher Tier Set.

A function of the form fx a ( ) = x, where. A) y = 15(35)x b) y = 15(1.35)x c) y = 15(0.35)x d) y = 35(1.15)x Exponential graphs and using logarithms to solve equations.
