first find the value of function for 1 and 3 .then use this formula average rate of change=(y2-y1)/(x2-x1)

thanks guys

if not: y = mx + c m is the gradient... which is the rate of change
Jack1
  • Jack1
in this case: y = 2x + 1 so c = 1 and m = 2...

The average rate of change is given by: \[a.r.c. = \frac{f(x_1)-f(x_0)}{x_1-x_0}\]
