20. The function f is continuous at x = 1. Vx + 3 -. - V3x + 1 for x 1 x - 1 If f(x) = k for x = 1 then k = 1 (A) 1 (B) , (C) -2 (D) None of these,

If a coffee filter is dropped, its velocity after t seconds is given by v(t)=4(10.0003t) feet per second. What is the terminal velocity, and how long does it take the filter to reach 99 of terminal velocity? Use a table increment of 0.1 and given your answer to the nearest tenth of a second.

Consider this function f(x)=x^2 -4x+a. If x<3 f(x)= 3x^2 -7x-2a. If x>3 f(x)= 23-4b            If x=3 Suppose I tell you that f(x) is continuous at x=3. Find a and b

Please classify the Type of Discontinuity of the following functions:
