I'm confused on the multiplying a function with a unit step function section. I understand up until the graph section for 3t. I know why it is a straight line, but did you figure out to start it at 10? What numbers did you plug in to get at 10 and how do you decide which number to plug in to give you the slope? Thank you

The reason is quite simple. The function is 3t, or you could consider that to be denoted as 3(t). Since t is the x axis, you can just think of it as 3(x) if you want. To draw the graph, you substitute the t axis coordinate into the function. So in this case, because the unit step function is multiplied by 3(t) and the graph for 3(t) starts at t=4, the first U point is at 3(4) = 12. Then the next one is at t=5 so 3(5) = 15, then 3(6) = 18, and finally 3(7) = 21. You could keep going but usually 2-4 points is enough for showing the graph. In the second example, the graph portion for 3(t) starts at 0 and ends at 4, so the points are 3(0) = 0, 3(1) = 3, 3(2) = 6, 3(3) = 9, and 3(4) = 12, and at that point the step function turns "off".

Thank u

maam, what about u(x)-u(x-1)?
