Section 3.2: Domain and Range of graphs of functions #1-10: Use the vertical line test to determine if the graph represents y as a function of x. 1) 3) 5) 7) 9) #11 – 2: Determine whether the equation defines y as a function of x. Hint, solve the equation for y and sketch a graph using your calculator, then apply the vertical line test. 11) y = x2 13) 𝑦 = √𝑥 + 2 15) y2 +x2 = 9 17) x = y2 #19 – 38: Find the domain and range of function. Write your answer in interval notation. 19) 21) 23) 25) 27) 29) 31) 33) 35) 37) #39 – 53 Use algebra to find the domain of each function. Write your answer in interval notation. 39) 𝑓(𝑥) = √𝑥 − 2 41) 𝑔(𝑥) = √3𝑥 + 12 43) 𝑓(𝑥) = 𝑥+2 𝑥−3 45) 𝑓(𝑥) = 2 𝑥 2 +6𝑥−7 47) g(x) = 2x - 10 49) g(x) = x2 + 5 51) f(x) = x2 + 2x - 15
