The value V of an item t years after it is purchased is given below. Use a graphing utility to graph the function. V = 6,000e-0.6277t, 0t 10

V=6,000e0.62t,0t10 (a) Find the rates of change of V with respect to t when t=2 and t=5, (Round your answers to two decimal places.) v(2)=v(s)= (b) Uhe a graphing valify to groph the tangent lines to the function when t=2 and t=5, (hound your coefficients to two decimal places. Selpet Upclate Graph to see your response plotted on the vcreen. Silect the submit button to grade your resoone.) tangent at t=2v= tangent at t=5v=
