Jack and Nina are graphing two equations on a coordinate grid. Jack has graphed the equation y = 2x. If Nina graphs y = 5x, wher
e will her graph be in relation to the graph Jack made? A) For all x > 0 the graph will be higher. B) For all x > 0 the graph will be lower. C) For all x the graph will be higher. D) For all x the graph will be lower.
What you can do for this case is to evaluate some points in both functions to realize the behavior: x 5x 2x -2 -10 -4 -1 -5 -2 0 0 0 1 5 2 2 10 4 We have then: For all x> 0 the graph will be higher answer: A) For all x> 0 the graph will be higher.
