Question

will fan and medal please help

Answer 1

Whats the problem?

Answer 2

For the function y = f(x), what is the ordered pair for the point on the graph when x = 3n - 4?

(3n - 4, f(n))

(3n - 4, f(3n - 4))

(x, f(3n))

(x, 3n - 4)

Answer 3

@Lexi00

Answer 4

i would say the first one but not100% sure

Answer 5

thanks for trying but y do you say so

Answer 6

It's the last one.
(x, 3n-4)

Answer 7

Plug in the value of x where you see x.
(x, f(x))
(3n - 4, f(3n - 4))

Answer 8

The ordered pair (3n - 4, f(3n - 4)) means:
The point whose x-coordinate is 3n - 4, and whose y-coordinate is the function f(x) evaluated at 3n - 4.

Answer 9

For any function f(x), the ordered pairs are:
(x, f(x))
Since in this case x = 3n - 4, we replace x with 3n - 4,
and we get (3n - 4, f(3n - 4)).

Answer 10

thanks so much @mathstudent55

Answer 11

You're welcome.

Answer 12

Another way of remembering this.
The ordered pairs are usually (x, y).
In this problem you are told that y is the function f.
You are given that y = f(x).
Replace y with f(x) in the ordered pair, and you get (x, f(x))
Now, in this case, when x = 3n - 4, replace x with 3n - 4 in both x and in f(x), and you get our answer.
