the domain and range of the following functions:
a.
y=3-x+

domain: R (all real numbers)
range: R (all real numbers)
b.
y=-4x%5E2
domain: R (all real numbers)
range: { y element R : y%3C=0 } (all non-positive real numbers)

c.
f%28x%29=abs%28x-8%29

domain: R (all real numbers)
range: { f element R: f+%3E=0 } (all non-negative real numbers)

d.
g%28x%29=-2%2F3
domain: R (all real numbers)
range:{ g element R : g+=-2%2F3 }
