London is standing in a stadium and has the option of running up a staircase or down a staircase for exercise. The function f(x) = 25 (16x| + 4x) will determine how
many calories London will burn if she runs up 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.
f(-50) =
means if London runs
50 stairs, she will burn
calories. This interpretation
in the context of the problem.
f(12)
means if London runs
12 stairs, she will burn
calories. This interpretation
in the context of the problem.
