What is the range of the following function ?
Graph including points (negative 2, 7), (negative 1, 0), (0, negative 5), (1, negative 8), (2, negative 9), (3, negative 8), (4, negative 5), (5, 0), (6, 7).

Best ResponseYou've already chosen the best response.1Have you noticed the  and _ key in your keyboard above the P key? You can write 2 instead of negative 2. It's much faster and easier to read.

Best ResponseYou've already chosen the best response.1To answer your question. The range of a function is the set of all the values used in the ycoordinate.

Best ResponseYou've already chosen the best response.0so that would be 7, 0, 5, 8, 9, 8, 5, 0 and 7?

Best ResponseYou've already chosen the best response.1These are the points you wrote above. \((2, 7), (1, 0), (0, 5), (1, 8), (2, 9), (3, 8), (4, 5), (5, 0), (6, 7) \)

Best ResponseYou've already chosen the best response.1In this case, those individual points are not important. You want the range of the entire function. What are all the ycoordinates that this function uses?

Best ResponseYou've already chosen the best response.1From the graph, it looks like the lowest ycoordinate is 9 from the point (2, 9) which is the vertex of the parabola.

Best ResponseYou've already chosen the best response.1As the two branches of the parabola go up, y in each ordered pair can take any number that is greater than 9.

Best ResponseYou've already chosen the best response.1That means the range is all real numbers greater than or equal to 9. Range: \( \{All ~y, such ~that ~y \ge 9 \} \)
