Answer all the problems please.

(1 point) The graph of f(t) is given below (Click on graph to enlarge) a. Represent f(t) using a combination of Heaviside step functions. Use h(t – a) for the Heaviside function shifted a units horizontally f(t) = help (formulas) b. Find the Laplace transform F(s) = L {f(t)) for s 0. F(s) = L {f(t)) = help (formulas) (1 point) Find the inverse Laplace transform of 7s F(s) = s2-15-12 f(t)-H(t-7)*(1/7% . (Use step(t-c) for uc(t) .) (4(t-7))-1/7*eX-3(t-7))) (1 point) Find the Laplace transform of f(t) -6u4(t) – 4u7(t) – 5ug(t) F(s)S (-15/2)
