Question

Determine whether the given function is linear. f(x) = 3 + 1/3x

Answer 1

x = -1/9 is the answer i believe

Answer 2

you can either graph this or plug in values.

`f(x)=3+(1)/(3)x`

`f(-1)=3+(1)/(3)(-1)\\\\f(-1)=3-(1)/(3)\\\\f(-1)=2\ (2)/(3)\\\\f(0)=3\\\\f(1)=3\ (1)/(3)`

`\therefore` we can conclude that this function is linear.

Also here is a graph
