Kaylee is standing in a stadium and has the option of running up a staircase or down a staircase for exercise. The function f(x)=\frac{1}{50}\big(\left|6x\righ t|+4x\big)f(x)= 50 1 (∣6x∣+4x) will determine how many calories Kaylee will burn if she runs up xx steps. Use a value for xx if she runs the stairs. Find and interpret the given function values and determine an appropriate domain for the function. F(-45)=f(−45)= , means if Kaylee runs 45 stairs, she will burn calories. This interpretation in the context of the problem. F(11)=f(11)= , means if Kaylee runs 11 stairs, she will burn calories. This interpretation in the context of the problem. F(10.5)=f(10.5)= , means if Kaylee runs 10.5 stairs, she will burn calories. This interpretation in the context of the problem. Based on the observations above, it is clear that an appropriate domain for the function is .
