Determine the average rate of change of the function y(t) = .5 t ^ 2 + 80 t + -10 between x and x + D< time clock at function this of change rate instantaneous the determine to it use and expression your Simplify>x.I found this definition of Average rate of change =(f(d)-f(a))/(b-a) = Dy/Dx
Y`=t+80 or f(x+D)-f(x)/ D x
You're on the right track, but you have a specific function y(t).
What's the expression for y(x + D)?
So what is your expression for (y(x+D) - y(x) ) / D?
What are the growth rate, growth factor and principal function P(t) for an initial investment of $ 990 which is compounded annually at 10% interest?
Growth rate = 10%and the growth factor 1.1 p(t)= 990(1.1^t)
Good, but you didn't go quite far enough with the first question.
