MAT111A - College Algebra Quiz 3 (20 Questions)The following questions were adapted from Blitzer, R.(2018). College Algebra (7th ed).NOTE: Be sure to show your work for the solution to each question. Partial credit may be given, even if the final answer is not correct, as long at the proper concepts are being depicted.Scoring: 2 points each1.Give the domain and range for this relation. Describe whether the relation is a function or not.{(3, -2), (5, -2), (7, 1), (4, 9)}The Domain is {3,5,7,4}The Range is {2,2,1,9}2.Using the coordinate template below, draw a graph with the square root functions, f and g, in the same rectangular coordinate system. Use the integer values of x given to the right of each function to obtain ordered pairs. Once the functions are graphed, describe how the graph of g is related to the graph of f.f(x) = x (x = 0, 1, 4, 9) g(x) = x+2 (x = -2, -1, 2, 7) the graph of g is obtained by horizontal shifting of the graphof f two units to the left.

3.Evaluate the graph below and determine if y is a function of x. Describe the method used for this determination.y is a function of x. from the graph, it is seen that every element of x corresponds to only 1 element of y. for a function, each element of x should be paired to only 1 element of y, (i.e. each element in the domain must correspond to exactly 1 element in the range). any vertical line drawnintersects the graph only once hence y is a function of x.4.Use the graph below to determine:a. the function’s domain = (,+)b. the function’s range =¿c. the x-intercepts, if any ¿1d. the y-intercept, if any ¿1e. the function’s values f(4)and f(3)f(4)=3f(3)=4

5.Use the graph below to determine:a. the intervals on which the function is increasing, if any =(,1)b. the intervals on which the function is decreasing, if any = nonec. the intervals on which the function is constant, if any = (1,+)6.Examine the graph below, use possible symmetry to determine whether the graph is the graph of an even function, an odd function, or a function that is neither even nor odd.The graph of an odd function
