Question

how would this function appear on a graph f(x) = -3x?

Answer 1

Functions of the form
f(x) = ax + b, where a is not 0 and b is any real number, then it will always be a line.

Answer 2

oh i see what about this one f(x) = 3 - x

Answer 3

Its still a line, you would just rearrange it as f(x)=-x+3

Answer 4

Here's graphs of those two functions

Answer 5

thank you thats what i needed(:
