Exercises 39-42: Write the requested equation. Then graph the given equation and your equation. 39. Reflect f(x) = Vx+ 1 across the x-axis. 40. Reflect f(x) = |x| – 1 across the x-axis. 41. Reflect f(x) = x² - x across the y-axis. 42. Reflect f(x) = V-x + 1 across the y-axis.

O Payment Plan A and Payment Plan B have the same initial balance. Use the graph of Function 1 to complete the table. Function 1 Ay The equations of 3 other functions are given below. Indicate whether the slope of each function is greater than, equal to, or less than the slope of Function 1. Place a check () to identify either greater than, equal to, or less than for each function. Functions y = 4 + x y = 7 y = x + 2 Greater than Equal to Less than Determine which relation is NOT a function.
