If a function is defined by the formula y = -x +3 and its domain is given by the set {-4,0,8), the
of the following sets gives the function's range?

step-by-step explanation:

b and c

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
