Use technology to graph the pairs of functions on the same set of axes with -3 x 3. f1(x) = 1.6x, f(x) = 1.8x Identify which graph corresponds to which function. O f(x) starts lower than f(x), but finishes higher than f(x). Of(x) is identical to f(x). f(x) starts higher than f(x), but finishes lower than f(x). O f(x) is always lower than f(x). Of(x) is always higher than f(x).
