For x > 0, which of these statements best describe the graph of y = x0.25? |
|
Answer» Answer: The slope is GREATER than zero and it is decreasing Explanation: The equation is y = x^0.25 This can also be WRITTEN as y = x^(1/4). Since x>0 therefore we can say that x = 1 or 2 or 3 or 4 when x = 1, y = 1 when x = 2, y = 1.1892071 when x = 3, y = 1.316074 when x = 4, y = 1.4142136 the slope between x = 1 and x = 2 is equal to (1.1892071) / 1 = .1892071 the slope between x = 2 and x = 3 is equal to (1.316074 - 1.1892071) / 1 = .13268669. the slope between x = 3 and x = 4 is equal to (1.4142136 - 1.316074) / 1 = .0981396. The slope is greater than zero and it is decreasing. |
