Question

Rewrite 3x + 4y = 10 using function notation

Answer 1

f(x)=10-3x/4

Answer 2

Solve for y and then replace 'y' with f(x)


\[\Large 3x + 4y = 10\]


\[\Large 4y = 10-3x\]


\[\Large 4y = -3x+10\]


\[\Large y = \frac{-3x+10}{4}\]


\[\Large y = \frac{-3x}{4}+\frac{10}{4}\]


\[\Large y = -\frac{3}{4}x+\frac{5}{2}\]


\[\Large f(x) = -\frac{3}{4}x+\frac{5}{2}\]
