- Does a Limiting Value Occur? A rocket ship is flying away from Earth at a constant velocity, and it continues on its course indefinitely. Let D(t) denote its distance from Earth after t years of travel. Do you expect that D has a limiting value?arrow_forwardWhich statement below is true? O If a function is not differentiable then it must be discontinuous as well. O You cannot use limits to compute the derivative at a discontinuous point. O Secant lines can be used to compute the derivative of a discontinuous point. O A discontinuity does not always make a function non-differentiable.arrow_forwardUSE THE LIMIT DEFINITION OF DERIVATIVE: A wire 10 cm long is cut into two pieces, one of length ? and the other of length 10 − ?. Each is bent in a shape of a square. (a.) Find a function that models the total area enclosed by the two squares as a function of ?. (b.)

- 1. Sketch a function that has a horizontal tangent line for all values of x. Explain how you arrived at this graph. 2. Sketch a function that is continuous for all real numbers and has horizontal tangent lines at (0,0) and (3, 3). Give a formula for the function, explaining how you arrived at this particular example.arrow_forwardLet f (x) be the function given below. Find all x values where f(x) is discon- tinuous. A. x = 2,3,4 ОА B B. x = 2,4 C. x = 4 D. x=2 E. x = 3,4 C 4 if x 4 MacBook Airarrow_forwardDirection: Let y - fx). Note any pattern and use this to determine the derivative of the other functions. Guide Questions: Function Derivative 1. Based on the pattern, what is the denivative of a function in the form f(x) =x? We call it the "derivative of f(x) = x f(x) =2x fx) - x f(x) = 3x2 a power rule". f(x) = x4 f(x) - 4x3 2. How does it compare to the previ ous method (that makes use of de- rivative definition)? ffx) = x5 f(x) = x6arrow_forward
