Question

Graph the function. y=2x

Answer 1

This is a linear function.  If x=0, y=0; if x=2, y=4, etc.  Plot the points given by these coordinate pairs:  (0,0), (2,4), ....

The resulting graph is the straight line drawn thru these points.  It has a slope of 2 and a y-intercept of 0.


If you meant y = 2^x, then you have an exponential function, which is an entirely different matter.
