How to do composition of functions​

Mathematics

<h2><u><em>If you rather have the link to get this info lmk!!</em></u></h2>

Example: f(x) = 2x+3 and g(x) = x2

"x" is just a placeholder. To avoid confusion let's just call it "input":

f(input) = 2(input)+3

g(input) = (input)2

Let's start:

(g º f)(x) = g(f(x))

First we apply f, then apply g to that result:

Function Composition - (g º f)(x) = (2x+3)2

What if we reverse the order of f and g?

(f º g)(x) = f(g(x))

First we apply g, then apply f to that result:

Function Composition - (f º g)(x) = 2x2+3

We get a different result!  When we reverse the order the result is rarely the same.  So be careful which function comes first.

Answer:

Interest: 3.25%

$ Amount after 3 Years: $1,317.00

Step-by-step explanation:

If Robert invest 1200 dollars in the CD for a period of 3 years, he will earn 3.25% annual interest.  

First, converting R percent to r a decimal

r = R/100 = 3.25%/100 = 0.0325 per year.

Solving our equation:

A = 1200(1 + (0.0325 × 3)) = 1317

A = $1,317.00

The total amount accrued, principal plus interest, from simple interest on a principal of $1,200.00 at a rate of 3.25% per year for 3 years is $1,317.00.

I hope this helps. If you have any more questions, please feel free to post them and someone will be able to help you, whether it's myself or others. Please leave a like, rating, and if possible, Brainliest. Have a great day!

If $95 is put in an account that gets 6% and I add $18 at the end of each year, how much will I have at the end of 11 years?
Temka [501]
6% of $95 = $5.70
multiply $5.70 by 11 years = $62.70 <— interest gained over 11 years
multiply $18 by 11 years = $198 <— total added over 11 years 
add $95 + $62.70 + $198 = $355.70
there will be a total of $355.70 in your account after 11 years
