F(x) is the function that determines the absolute value of the cube of the input.

Question

1.) Evaluate: F(5)
2.) Evaluate: F(-7)
3.) Determine: F(5)⋅F(-7)

Answer 1

f(x) = |x^3|
f(5) = |5^3| = |125| = 125
work the others in the same way, recalling that
|x| = x if x >= 0
|x| = -x if x < 0
the cube of a negative value is also negative (but that doesn't really matter here, since we're taking its absolute value)
