any vertical line can only cross the graph at once at any point to be a function b) k → vertical shift (up and downn). ﹣k shifts down, + k shifts up c) as one variable increases, so does the other d) the x-values (input) of a relationship 13) Range a) a relation where each input is related to exactly one output; the independent x-values do NOT repeat b) the y-values (output) of a relationship c) use to find if a graph is function or not; any vertical line can only cross the graph at once at any point to be a function d) a number between ﹣1 and +1 that measures the strength and direction of the relationship between two variables 14) Correlation Coefficient, r a) m/A/a → vertical stretch/compression (shrink). m/A/a > 1 vertical stretch,  0 < m/A/a < 1 vertical shrink b) as one variable increases, you cannot tell what the other variable is doing c) the x-values (input) of a relationship d) a number between ﹣1 and +1 that measures the strength and direction of the relationship between two variables 15) Function Notation a) a set of points on a graph b) function notation is a way to denote the input, x, and the output, y... f(x) = y c) as one variable increases, the other decreases d) the variable whose value does NOT depend on another value (x-variable)  16) Horizontal Transformation/Shift a) as one variable increases, so does the other b) data that has no breaks; connected line on a graph c) h → horizontal shift (left and right). ﹣h shifts right, + h shifts left d) as one variable increases, you cannot tell what the other variable is doing 17) Vertical Transformation/Shift a) function notation is a way to denote the input, x, and the output, y... f(x) = y b) k → vertical shift (up and downn). ﹣k shifts down, + k shifts up c) m/A/a → vertical stretch/compression (shrink). m/A/a > 1 vertical stretch,  0 < m/A/a < 1 vertical shrink d) specific data points; dots NOT connected on a graph 18) Vertical Stretch & Vertical Shrink (Compression) a) a relation where each input is related to exactly one output;
