- Determine if each statement is true or false. If the statement is false, provide a brief explanation: a) There exists x = R such that √x2 = -x. b) Let A = {x = ZIx = 1 (mod 3)} and B = {x = ZIx is odd}. Then A and B are disjoint. c) Let A and B be subsets of a universal set U. If x = A and x/ € A - B,then x = An B.| E d) Let f : RR be defined by f (x) = 1 x + 2 1. Then f is surjective.arrow_forwardWrite the negation of the definition of an injective functionarrow_forwardLet U= {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}, A = {xeU Ix is a multiple of 3}, and B = {x = UIx = 0 (mod 2)}.

- Use the figure for Exercises 1-2. Suppose you use geometry software to construct a secant CE and tangent CD that intersect on a circle at point C. File Edit Display Construct Transform Measure Graph Window Help D 1. Suppose you measure /DCE and you measure CBE. Then you drag the points around the circle and measure the angle and arc three more times. What would you expect to find each time? Which theorem from the lesson would you be demonstrating? 2. When the measure of the intercepted arc is 180°, what is the measure of the angle? What does that tell you about the secant?arrow_forwardQ.3.2 A sample of consumers was asked to name their favourite fruit.
