Use this chart to answer questions 1 – 4 x y 1) What is the domain? 3 -2 5 4 -2 3 6 -1 3) Is this a function? 3 4 For problems 5 – 10 use 2) What is the range? 4) Why or why not? f(x) = 3x – 5 & g(x) = x2 – 4 5) f(7) = 6) f(-4) = 7) f(3y) = 8) f(2x-5) = 9) f(g( – 3)) = 10) g(f( 4)) = Find the value of x using f(x) = 3x – 5 11) f(x) = - 26 12) f(x) = – 4 13) For each equation pick five values of the domain, and solve for the range. Then graph the four points.(for and b pick 0, 2 positives, and 2 negatives) a) y = 2x – 5 b) y = x2 + 3 14) For this one use the domain of all numbers with x = 1 up to x = 10. Graph it! y 15) Which of the four points below are solutions to the equation 2x – 3y = 5 ? a) (4,1) b) (-2, -3) c) (5,2) d) (2.5,0) 16) Give an example of an equation that is not a function. Explain why it isn't a function. 1 x
