3 Let f (2) = 3x-+9. 2-9 Find each of the following: x-intercept(s): Domain of f (x): y-intercept: Hole(s): Factor/Cancel f(x) here: HA: VA(s): as x -> oo, y -+ as x -> -0o, y - Use the number line below the graph to draw a sign chart for (the simplified version of) f(x). Then put all of these things together to make a sketch of the graph of f(x). -10 -9 -8 -7 -6-5 -4 -3-2 - 1 2 3 4 5 6 7 8 9 10 -10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 10 AFTER sketching, check your work by graphing f(x) at Desmos.com
