Function notation to 5x+2y=8

Question

I am try to figure out the answer in function notation to 5x+2y=8

Answer 1

Hello, Daisy,

     Function notation means that you write an equation with f(x)   f of x,  instead of "y."  For example,

 

4x + 2y =16      First,  solve for "y."     Get rid of 4x from both sides of equation:

 

     4x—4x +2y= -4x +16      2y=-4+16    

 

Find "y" by dividing every term by the number next to "y."       2y/2    =  -4/2 (x)   +16/2

 

Simplify:      y= -2x   +8        Now write with functional notation:    f(x)= -2x + 8

 

Just do your example using the steps that I have shown you, and you will have the answer.

 

I hope that I have helped.                     Susan C.
