Is there anything wrong with

Mayerlin is standing in a stadium and has the option of running up a staircase or down a staircase for exercise. The function f (x) = 50 (|7x| + 5x ) will determine how many calories Mayerlin will burn if she runs up a steps. Use a negative value for x if she runs down the stairs Find and interpret the given function values and determine an appropriate domain for the function. Answer Attempt 2 out of 2 f(-30) = 1.2 , means if Mayerlin runs down ~ 30 stairs, she will burn 1.2 calories. This interpretation makes sense in the context of the problem. f (25) = 6 means if Mayerlin runs up 25 stairs, she will burn 6 calories. This interpretation makes sense in the context of the problem. f (32.5) 7.8 , means if Mayerlin runs up 32.5 stairs, she will burn 7.8 calories. This interpretation makes sense in the context of the problem. Based on the observations above, it is clear that an appropriate domain for the function is all real numbers
