Part A (Short Answer): Answer each question in the space (blank) provided. Only the final answer will be (9 marks) marked. #1. A function is a set of ordered pairs but for every value of y, there is only one value of x (T/F). #2. Which test is used to show that a relation is a function; vertical line test or horizontal line test? #3. State the domain of the following function y = 4.9(t - 6.5)2 + 8. #4. State the range of the following function y = 2x + 3. #5. The minimum value of y = 2x + 3 #6. If f(x)=2x-4, find the value of x when f(x) is 21. #7. Define the nature of the roots for f(x) = 2x2 + 12x + 18 #8. If (2g -7) (3g +11) =0, then the value of g is: #9. What is the name of the technique use to solve for g in #8 Part B Full Solution Answers: 1. If g(x) = x2 -3x +5, find (a) g(-3) [2 marks] (b) x if g(x) =15 [4 marks]
