- Consider the following initial value problem. a) Find the solution y(t) in an explicit form. b) Use the theory of limits to find the behavior of y(t) as t approaches -infinity and +infinity.arrow_forwarda. Show that if the position x of a moving point is given by a quadratic function of t, x = At2 + Bt + C, then the average velocity over any time interval [t1, t2] is equal to the instan-taneous velocity at the midpoint of the time interval. b.

Use the derivative f′(x)f′(x) to find the critical value of f(x)f(x) in terms of aa and bb (does this formula look familiar?) Use the second-derivative test to show that the critical value is a local maximum if a<0a<0 or a local minimum if a>0a>0. What determines whether the graph of f(x)f(x) is concave up or concave down?
