Curves in computer graphics is primarily used for which of the following function? A. To draw different types of objects onto the screen B. Zooming out a picture C. Copying a picture D. Zooming in a picture

A curve in the xy-plane is defined by the vector valued function f, of, tf(t) equals= open angle bracket, x, left bracket, t, right bracket, comma, y, left bracket, t, right bracket, close angle bracket⟨x(t),y(t)⟩, where x, left bracket, t, right bracketx(t) equals= 5, cosine, left bracket, minus, 4, t, right bracket5cos(−4t) and y, left bracket, t, right brackety(t) equals= t, to the power minus 4 , plus, 3t −4 +3 for t, is greater than, 0t>0. What is start fraction, d, squared, y, divided by, d, x, squared, end fraction dx 2 d 2 y​ in terms of tt?

The graph of a function g is shown.The x y-coordinate plane is given. A function labeled y = g(x) with 4 parts is graphed.The first part is a curve, enters the window in the second quadrant, goes up and right becoming less steep, crosses the y-axis at approximately y = 2.5, and ends at the open point (2, 3).The second part is a curve begins again at the open point (2, 1), goes up and right becoming less steep, and ends at the open point (5, 2).The third part is the closed approximate point (5, 1.2).The fourth part is a curve, begins at the open point (5, 2) goes down and right becoming more steep, and exits the window in the first quadrant.Use it to state the values (if they exist) of the following:(a)  lim x → 2− g(x)(b)  lim x → 2+ g(x)(c)  lim x → 2 g(x)(d)  lim x → 5− g(x)(e)  lim x → 5+ g(x)(f)  lim x → 5 g(x)SolutionLooking at the graph we see that the values of g(x) approach as x approaches 2 from the left, but they approach as x approaches 2 from the right.Therefore (a) lim x → 2− g(x) =     and    (b) lim x → 2+ g(x) = .Since the left and right limits are different, we conclude that (c) the limit as x approaches 2 of g(x) does not exist.The graph also shows that (d) lim x → 5− g(x) =     and    (e) lim x → 5+ g(x) = .This time, the left and right limits are the same and so, by this theorem, we have (f) lim x → 5 g(x) = Despite this fact, notice that g(5) ≠ 2.

Question 3Based on the lectures, in the following picture, which curve corresponds to the expected behavior in theory, and which one corresponds to the behavior we get in practice? This when using plain neural networks.

In Exercises 13–16, find and sketch the level curves ƒ(x, y) = c onthe same set of coordinate axes for the given values of c. We refer tothese level curves as a contour map.13. ƒ(x, y) = x + y - 1, c = -3, -2, -1, 0, 1, 2, 3
