Question

Someone help me please? Medal for answer!

4. Graph the function
F(x) = -2x/3 + 400

Answer 1

It is a line. Locate two points and draw your line. The intercepts are good starters.
(0,400) (600,0)

Answer 2

@radar is there a difference in the answer when you take the Y from the equation Y = -2x/3 + 400 and replace it with f(x) = -2x/3+400?

Answer 3

The graph will be the same, you see you are letting the vertical axis (y) represent f(x).
Also, I would graduate the graph in increments of 50
