Done Test 2 Review - Ch. 7 & 8-1.docx ['1] 20. Determine whether the set of ordered pairs is a function. Then, state the domain and range. 1) {(0, 0), (2, 0): (57 0), (8, 0), (9, 0)} 2) {(1, 7), (6, 3)7 (8, 2), (1, 8), (67 1)} 21. Given F(x) : x2 + 2x 7 3, evaluate F63) 22. What is the domain of the function? Write the answer in set- builder notation. l 1) gm ' E 2) fm = 3x 5 23' f(\\')=.\\':4.\\'+1 1) Graph the function. First plot the ordered pairs of the function for the given values of the independent variable. Then connect the points to form the graph. x=5, 4, 3, 2, 1, 0,1 2) Estimate the domain and range from the graph. Write the answers in setbuilder notation
