Q. Find the average rate of change of g(x)=−3x+8 between x=2 and x=2+h, where h=0.Simplify your answer. Your answer may be a number or an expression in terms of h.
Calculate g(x): Calculate g(x) at x=2.g(2)=−3(2)+8=−6+8=2.
Calculate g(x+h): Calculate g(x) at x=2+h.g(2+h)=−3(2+h)+8=−6−3h+8=2−3h.
Find average rate of change: Find the average rate of change using the formula: [g(x2)−g(x1)]/(x2−x1).Here, x1=2 and x2=2+h.Average rate of change = [g(2+h)−g(2)]/[(2+h)−2]=[(2−3h)−2]/h=(−3h)/h=−3.
