Question

Which of the following equations represents the graph shown?

f(x) = x + 1
f(x) =x2/3x
f(x) =x3/2x

Answer 1

Notice that the x's in f(x)=x2/3x and f(x)=x3/2x will cancel...

therefore the problems become f(x)=2/3 and f(x)=3/2.
also remember the formula for the slope m=Rise/Run

Answer 2

also remember the formula y=mx+b where b is where the line crosses the y-axis. since it crosses at the origin(0) you will be looking where b =0
