Which equation represents a linear function? A)
y = 9 - x
B)
y = x2 + 1
o
y = x3 + 5
D)
y = Ixl - 9

it has the same slope and a different y-intercept

hope this : )

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)
