Question

You invest $1800 in a 10-year bond that gives you 3% interest on each year for 10 years.


a. Construct a function that represents the amount of interest, l(n) , earned after n years. What is the domain and range in this context? What is the input and output?

Answer 1

1800 * 10 * .03 = 540.
Make a function table ( x & y chart ).
Figure out the function rule.
Then the domain is side x and the range is side y.

Answer 2

ok for the domain it gives options either n<=540, 0<=n<=10,0<=n,n<=0, O<=n<=540
and range 0<=l(n)<=10, 0<=l(n), l(n)<=10,0<=l(n)<=540, l(n)<=540

Answer 3

ok the function has to be for the interest l(n) it says the function is incorrect :/
