Question

f(x)=-3x+4

Answer 1

I know that I would have to turn the f(x) into y=-3x+4 but I forgot how to do the rest

Answer 2

This is like you wrote 2+2=4
And?
What do you need?
f(2)=-3*2+4
f(x)=-3*x+4
f(b)=-3*b+4
What's your question?

Answer 3

Sketch a graph of y=f(x)

Answer 4

Make table for x and y
Put 0, 1, 2, 3 for x, and using function find y... Those are your points for the graph...
In this particular case you need just two points, but it's better always to do as much as you can...
Fair enough?

Good luck

Answer 5

Thank you

Answer 6

so I found out that one would be (0,4) and the other to be (1,1) correct?

Answer 7

then the slope would be -3
