Question

what is the domain of a function?

Answer 1

is the x of the function

Answer 2

the x-intercept?

Answer 3

no the possible solution that x can get

Answer 4

oh! ok thank you

Answer 5

What is the exact function you are dealing with ?

I am going to say to things,\
1) The value of x that makes the denominator be equal zero, is excluded from the domain
(example x=2 if the denominator is x-2)
2) The value that makes any root into an imaginary number.
(example if you have √(3-x) and x<3 )

Answer 6

its a big chart and then all this:
Part A: What does the x-intercept of the function for car 1 represent? (2 points)

Part B: What does the y-intercept of the function for car 2 represent? (2 points)

Part C: What is the domain of the functions for car 1 and car 2? (2 points)

Part D: What is the average rate of change from x = 20 to x = 30 for the function representing the motion for car 2? What does the value of this average rate of change represent? (4 points)

but I got it.

Answer 7

If you really think you gave me enough info ...

Answer 8

I said "but I got it" I wasn't asking for help on this, you just wanted to know. all I needed to know was the domain explination :)
