2.2 For each of the following systems, specify whether or not the system is: (i) linear and/or (ii) time-invariant. (a) y(t) = 3x(t − 1) (b) y(t) = t x(t) (c) dy dt + y(t − 1) = x(t) (d) dy dt + 2y(t) = t −[infinity] x(τ ) dτ (e) y(t) = x(t) u(t) (f) y(t) = [infinity] t x(τ ) dτ (g) y(t) = 2t t x(τ ) dτ

step-by-step explanation:

first i did work 2nd i did work and 3rd i did work

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.
