Graphing logarithmic expressions in exercise, sketch the graph of the function.
y = in(4 - x)

See the graph and explanation below.

Step-by-step explanation:

For this case we have the following function:

The domain for this function is given by:

since the natural log is not defined for negative numbers

,

We can calculate some points in order to see the tendency of the graph, we can select a set of points for example and we can calculate the values for f(x) like this

x=-3

x=-2

x=-1

x=0

This point correspond to the y intercept.

x=1

x=2

x=3

And that represent the x intercept

And then we can see the plot on the figure attached.

step-by-step explanation:

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true
