Sample Problem

a)Fill out the following table if j(x)=3/4e0.25x. Keep all answers rounded to two decimal places.

 

x

-3

-2

-1

0

1

2

3

j(x)

 

b)Is this an accurate graph of j(x)? (type Y or N in the blank)

 

 

Solution

a)Plug all the x-values in function j(x)=3/4e0.25x to get the table below.

 

 

x

-3

-2

-1

0

1

2

3

j(x)

0.35

0.45

0.58

0.75

0.96

1.24

1.59

 

b)Yes, if you plot all the points onto the graph, the graph will look exactly like the one given.

 It is an accurate sketch of j(x)!
