Discuss the relationship between functions, their inverses, and the results of function operations. choose one type of function operation (composition, sum or difference, product or quotient) and explore the related question. you may use equations, diagrams, or graphs to organize and present your thoughts.
choose any two specific functions that have inverses. use your chosen functions to answer any one of the following questions:
if the inverses of two functions are both functions, will the inverse of the composite
function made by the original functions also be a function?
if the inverses of two functions are both functions, will the inverse of the sum or difference of the original functions also be a function?
if the inverses of two functions are both functions, will the inverse of the product or quotient of the original functions also be a function?

let's add {f(x)=x+1}f(x)=x+1 and {g(x)=2x}g(x)=2x together to make a new function.

f(x)+g(x) =(x+1)+(2x)=x+1+2x=3x+1

let's call this new function hh. so we have:

{h(x)}={f(x)}+{g(x)}{=3x+1}h(x)=f(x)+g(x)=3x+1

we can also evaluate combined functions for particular inputs. let's evaluate function hh above for x=2x=2. below are two ways of doing this.

method 1: substitute x=2x=2 into the combined function hh.

h(x)

h(2)

​    

=3x+1

=3(2)+1

=7

​ since h(x)=f(x)+g(x)h(x)=f(x)+g(x), we can also find h(2)h(2) by finding f(2) +g(2)f(2)+g(2).

first, let's find f(2)f(2):

f(x)

f(2)

​    

=x+1

=2+1

=3

​  

now, let's find g(2)g(2):

g(x)

g(2)

​    

=2x

=2⋅2

=4

​  

so f(2)+g(2)=3+4=\greend7f(2)+g(2)=3+4=7.

notice that substituting x =2x=2 directly into function hh and finding f(2) + g(2)f(2)+g(2) gave us the same answer!

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23

144.50
