Absolute minimum question?

Question

Given the interval (-5 ≤ x ≤ 0.5) identify the absolute minimum value of the function:

a) y = -5 where x = -4
b) y = 2 where x = 0
c) y = 0 where x = -2
y = -2 where x = -1

Answer 1

all these are CONSTANT functions (y = k), and their minimum value is their ONLY value. y = -5 has -5 as its value EVERYWHERE, no matter what x is.
