Algebra II Ch. 1.2 Introduction to Functions

Math Antics: What are functions? Watch entire video! In the video, Rob mentioned "one-to-many." In our notes, we learned about "many-to-one." What's the difference? The _ of the function above is {-9, -8, 7, -6}. range domain output codomain The _ of the function above is {2, 6, 10, 14}. range domain input codomain What is the domain of the graph?Note: oo is used to represent infinity. [-1, oo) [-2, oo) (-1, oo) (-2, oo) What is the range of the graph?Note: oo is used to represent infinity. [-1, oo) [-2, oo) (-1, oo) (-2, oo) What is the range of the relation y = 2x² + 5x, if the domain is the set {-2, 0, 1, 2}? {-18, 0, 7, 26} {-18, 0, 8, 26} {-2, 0, 8, 18} {-2, 0, 7, 18} A function is defined by the equation y = -3x - 4. If the domain iswhat is the minimum value in the range of the function? -oo -7 -10 -19 What is the domain of f(x) = 2x All integers All real numbers x > 0 x < 0
