Question

What is the range of the function y = |x |?
x ≥ 0
y ≥ 0
all real numbers

Answer 1

The answer is B. y>0

Answer 2

The range is the set of values for y. Since y=|x|, y is always positive and increases without bound as x approaches +oo. Thus the range is:

y≥0 which can also be expressed as y=[0, +oo)
