Graph f(x)=3x

Problem

ƒ(x)=3*x

Solution

1. Identify the type of function. The expression ƒ(x)=3*x is a linear function in the form ƒ(x)=m*x+b

2. Determine the slope and y-intercept. The slope m is 3 and the y-intercept b is 0

3. Find the y-intercept point. Since b=0 the graph passes through the origin (0,0)

4. Calculate a second point using the slope. Starting from (0,0) move up 3 units and right 1 unit to find the point (1,3)

5. Draw a straight line through the points (0,0) and (1,3) to complete the graph.

Final Answer

ƒ(x)=3*x
