Hello : 
find : g(x) if   <span> f(g(x))=3x-7  and   f(x)=1/3x2

</span>  f(g(x)) = 1/3(g(x))2 = 3x-7
solve :  1/3(g(x))2 = 3x-7
(g(x))2 = 9x-21

Question 5 Unsaved
Otrada [13]

We can use the compound interest formula

F=P(1+i)^n

where

F=Future value of investment to be found

P=present value of investment ($1000)

i=interest per period (1/4 year)=0.04/4=0.01

n=number of periods (3 years * 4 quarters = 12)


Substitute or "Plug in" values, so to speak,

F=1000*(1+0.01)^12

use a calculator to do the sum

=1126.83 (to the nearest cent, and use the proper rounding rules)
