6. At a college, records show that the average person's grade point average, G(h),
is a function of the number of hours he or she studies and does homework per
week, h. The grade point average can be estimated by the function
G(h)=0.01h +0.2h+1.2, for 0sh58. What is the grade point average of the
average student who studies and does homework for 3 hours per week?

An amount of B was deposited in one of the investment bank accounts, whereby interest
of A% is paid annually. The amount is calculated, so thạt n= capital, cumulative after a
number of years based on the function d (x) = n (1 + m)*
n= time in years, m = annual interest.
a. Calculate the cumulative amount after 8 years.
B. How many years does it take to invest an amount equal to 3 times the capital?
c. Draw the function d (x).
B=951 RO
A=1%
