Question

4x+y=-10 in function form

Answer 1

y=-4x-10

Answer 2

f(x)=y=-4x-10, let's say f(x) is a function of x

Answer 3

and f(x) is expressed as y

Answer 4

\[\text{Rewrite the equation to isolate y.}\\
\ \ \ 4x+y=-10\\
\ \ \ y=-4x-10\\
\text{So, as a function, we write}\\
\ \ \ y(x)=-4x-10
\]
