Which of the relations has a domain of (-5,0,5)

(-5, ?), (0, ?), (5, ?)

Step-by-step explanation:

Nobody has taken a stab at this likely due to the answer choices being MIA, however, they aren't necessary because of the simplicity of the question. There's only ONE answer that'll match this format: (-5, ?), (0, ?), (5, ?)

Allow me to explain.

DOMAIN means the independent value. This means Input. This means X.

RANGE means the dependent value. This means Output. This means Y.

Relations are the comparison of one bit of information against another.

Functions are special types of relations in which you have an independent and dependent variable in a "relation," in which the value of the dependent variable will depend on the value of the independent variable.

The formatting of (x,y) is the position of that point on a x & y graph. X will be the input value, the domain, and y will be the output value, the range.

This question asks you which relation has a domain of the following numbers: -5, 0, 5.

There are three separate domains. In a function, a function MUST have EACH value of an independent variable associated to one value of a DEPENDENT variable.

Please keep in mind that this means x can never repeat, because this would cause conflict, however, y CAN repeat. Each and every independent variable must be associated to only one dependent variable.

This means you can't have something like (3, 4) and (3, 5) in a function, but you COULD have (3, 4) and (4, 4).

Returning focus to YOUR situation, you have three individual domain inputs, which means you MUST have three range outputs, which are allowed to be either different/separate or identical numbers, or a mix.

This means for every input you have an output. Your answer WILL take this format: (-5, Y), (0, Y), (5, Y).

It'll be the ONLY answer with EACH input variable (the first number in each of the parenthesis) beginning with -5, 0, and 5. The range/output can fluctuate, but that's entirely unnecessary to know. In my example, the Y can be any number between 0 and 9, but the first number (s) CANNOT change, or your answer will be wrong.

Hope this helps!

step-by-step explanation:

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
