What are the domain and range of the algebraic function you found by graphing the equation y = 36 – 3x? Please hurry I'm being t
pychu [463]

Answer:

Domain =(-\infty,\ \infty)

Range =(-\infty,\ \infty)

Step-by-step explanation:

Domain : Domain of a function f(x) is the set of all possible values of x for which f(x) exists.

Range : range of a function f(x) is the set of all possible values of f(x).

Here f(x)=36-3x

x can be any value from -\infty to \infty.

\forall\ x=a\ there\ exists\ f(x)\ such\ that\ f(a)=36-3a

hence possible value of x can be any value between -\infty and \infty

domain =(-\infty,\ \infty)

let y=-f(x)

y=36-3x\\3x=36-y\\\\\\x=\frac{36-y}{3}\\

so \forall\ f(x)=y\ there\ exist\ x\ \in(-\infty,\ \infty).

hence f(x) can have any value between -\infty\ to\ \infty..

Range =(-\infty,\ \infty)

Please help im confused on the last question on my warm up!
geniusboy [140]

Answer:

Choice B: Only (-1,-5)

Step-by-step explanation:

With this one, first the equation needs to be reduced into point-slope format.

y+5=2(x+1)

Distributive Prop.

y+5=2x+2

Carry over the 5 to the opposite side.

y=2x-3

Now, with the point slope form, it makes it easier to plug in the question choices to find which if any are correct.

Choice A: X is 5; Y is 10

y=2x-3

y=2(5)-3

y=10-3

y=7

This does not give a y value of 10, so it is false.

Choice B: X is -1; Y is -5

y=2(x)-3

y=2(-1)-3

y= -2-3

y= -5

This does give a y value of -5, so it is true. Choices C and D are therefore false as well, since only Choice B works.
