A. True or False Direction: Write T if the statement is true and F if the statement is false in the space provider before each number F 1. The set of abscissa is the domain. 2. The function notation of y = 3x + 6 is f(x) = 6x + 3. 3. A curve open downward is not a function. 4. Given that f(x) = 3x + 6, f(2) is equal to 12. 5. The set ordered pairs {(-2,0).(-1,4),(0,2),(1,4)} is a function. 6. The dependent variable is x and the independent variable is y. 7. The second elementy is called ordinate and set of ordinate is the range. 8. It is a function when the domains are repeated in the set of ordered pair. 9. The function notation of -x + y -1 = 0 is g(x) = x + 1. 10. The graph is a function if and only if vertical line intersects the graph at exactly one point​
