|x| is always >/= 0
If x = 0
y = 1
If |x| > 0 (that is a domain of all real x, positive or negative)
y < 1
so
domain is all real x
and
range is y </= 1
graph it
Pretend the parentheses are absolute value bars.
Find the domain and range of
y = -1/4(x) + 1
How would I figure this out? Thank you so much!
