f(x)=2x-3/x+4; g(x)=3 + 4x/2 - x
Answer by josgarithmetic(39627) (Show Source): You can put this solution on YOUR website!
The way to express the functions in pure text is like this:
f(x)=(2x-3)/(x+4) and g(x)=(3+4x)/(2-x)
Surrounding each with the triple curly brace rendering tags gives the expected appearance,
and
To answer the question, you have a couple of choices.
Form their composition and simplify. Is the result, x ?
OR
Select one of the functions. Let the function name be y, switch x and y, and solve for y. Is this result equivalent to the other function ?
