Tell whether the set of ordered pairs {(3, −6), (4, −9), (5, −12), (6, −15)} satisfies a linear function. Explain. No; there is no constant change in x that corresponds to a constant change in y.
Yes; there is a constant change in x that corresponds to a constant change in y.
Yes; there is no constant change in x that corresponds to a constant change in y.
No; there is a constant change in x that corresponds to a constant change in y.

1 + (6 / x - 1)

step-by-step explanation:

divide using polynomial division.

3

step-by-step explanation:

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)

the answer on ed. is:

c. "the graph of f(x) has exactly two x-intercepts."

hope i could someone! : )
