Question

Rewrite 3x + 4y = 10 using function notation.

Answer 1

f(x) is a way of writing the output of a function, also known as the dependent variable. You are probably used to seeing y in this place, but all you're doing is replacing y with f(x).


`3x+4y=10 \\ 4y=-3x+10 \\ y = (-3)/(4)x+ (5)/(2) \\ \\ f(x) = (-3)/(4)x+ (5)/(2)`
