A curve in the xy-plane is given by the parametric equations x(t) and y(t). The graph of x(t) is shown above on the left, and the graph of the derivative y′(t) is shown above on the right. Which of the following integral expressions gives the length of the portion of the curve described by the parametric equations for 1≤t≤3 ?

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

you,

mrb

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.

pls refer ro the top for answer
