Graph f(x)=4x

Problem

ƒ(x)=4*x

Solution

1. Identify the type of function. The function ƒ(x)=4*x is a linear function in the form ƒ(x)=m*x+b

2. Determine the slope and y-intercept. The slope m is 4 and the y-intercept b is 0 meaning the line passes through the origin (0,0)

3. Calculate additional points to define the line. For x=1 ƒ(1)=4*(1)=4 giving the point (1,4) For x=−1 ƒ*(−1)=4*(−1)=−4 giving the point (−1,−4)

4. Plot the points (0,0) (1,4) and (−1,−4) on a coordinate plane and draw a straight line through them.

Final Answer

ƒ(x)=4*x
