###### Question:

Show how to graph please.

1. Graph the function f(t)=3t(h(t−4)−h(t−9)) for 0≤t<∞0≤t<∞. Use your graph to write this function piecewise as follows:
 3t(h(t−4)−h(t−9))={ if 0≤t<4,0≤t<4, if 4≤t<9,4≤t<9, if 9≤t<∞.9≤t<∞.
2. Evaluate f(6.5)

f(6.5)=
a Graph the function f(t) = 3t(h(t-4) _ h(t-9)) for 0 < t < oo. Use your graph to write this function piecewise as follows: 3t(h(t -4) h(t 9)) if9<t<oo. help (formulas) b. Evaluate f(6.5) f(6.5) help (formulas)
