# Graphs and Functions : Asymptotes, X- and Y-Intercepts, Inverses, One-to-one and pH and H+ Ion Concentration

1. graph f(x) =

+ 5x+ 4

be sure to label all the asymptotes and to list the domain the x and y- intercept

2. f(x) = +3, x

- sketch the graph and use the graph to determine whether the function is one to one

-if the function is one to one find a formula the inverse

3. In chemistry the pH of the substance defined as

pH = -log [H ],

find the pH of each of the substance

substance hydrogen ion concentration

a) juice 1.6x 10

b) hire rinse 0.0013

c) mouthwash 6.3 x 10

d) eggs 1.6 x 10

e) tomatoes 6.3 x 10

4. solve using any method

ln(ln x) = 2

1. graph f(x) =

+ 5x+ 4

be sure to label all the asymptotes and to list the domain the x and y- intercept

Use Maple, we get the following graph:

The horizontal asymptote is y=0

Two vertical asymptotes are x=-1 and x=-4

x-intercept is ...
