Question

calculator, graph the following functions, in one viewing window. Don't graph them all e. Enter one in the Y=list, look at its graph, enter another, look at the two graphs, etc. (Do You know where the absolute value function is on your calculator?) y = x, y = x + 2, y = x + 5, y = |x-1, y = x - 3 1. (1) Describe what the graph of y = f(x) = x+d will look like for any real number d. As before, graph the following functions. y = xl, y = |x+1, y = x + 3), y = x -21, y = x - 4 2. (1) Describe what the graph of y = f(x) = |x-c will look like for any real number c. As before, graph the following functions. y=[xl, y = 2xl, y = 4(xl, y ==}x), y = Xl, y=-=[xl, y=-3|x/ 3. (1) How is the graph of y = f(x) = ax related to the graph of y = f(x) = |x for any real number a? As before, graph the following functions. y = |xl, y = (3x), y =|5x|, y = x, y=-* 4. (1) How is the graph of y = f(x) = |ax| related to the graph of y = f(x) = |xt| for any positive real number a? 5. (1) What do you think will happen if a is negative? 6. (1) Evaluate the difference quotient for f (x) = 3x - 2x+1. 129
