27. Graph the equation and if the graph determines y as a function of x, find the domain and use the graph to determine the range of the function. y = x2 +x, - 25x51 46. Consider the graph of y = g(x) given in Section 3.3 Exercise 34 of the text. Observe that the point (-2, -3) is the lowest (minimum) point on this graph. domain: all real numbers; O a. After the graph of y = 79(-T - 2) + 1 is created by a series of transformations to y = g(x), range: -4 sys 2 where will the lowest (minimum) point be located? domain: -2 S x $1; The annual dues of a union are as shown in the table. O b . O a. (4, -1/2) range: -+ sys 2 Employee's Annual Salary Annual Dues O b. (0, -1/2) less than $8000 $60 O c. domain: all real numbers; range: all real numbers O c. (-4, 5/2) 39 $8000 or more but $60 + 1% of the salary less than $15,000 O d. (0, -1) in excess of $8000 O d. domain: -+ sys 2; $15,000 or more $130 + 2% of the salary range: -2 S x 5 1 in excess of $15,000 28. Graph the equation and if the graph determines y as a function of x, find the dom Express the annual dues d as a function of the salary S. use the graph to determine the range of the function 60 if S 15, 000 a. domain: all real numbers; 60 if S 15, 000 Ob. range all real numbers 60 if S 1; O c. d(S) = 60 + 0.01S if 8, 000 15, 000 range: all real numbers 60 if S 15, 000
