Question

For the function y=f(x), what is the ordered pair for the point on the graph when x=2m+3?

(x, f(m))
(x, 2m+3)
(2m+3, f(m))
(2m+3, f(2m+3))

Answer 1

If x = 2m+3, what is the x-coordinate?

Answer 2

The answer to the equation?

Answer 3

If you read the question, it's talking about a function that has an ordered pair. And x = 2m+3. You want to write the ordered pair.

So an ordered pair has an x-coordinate and a y-coordinate.

What will be the x-coordinate?

Answer 4

m? (I'm not very good at math)

Answer 5

It says that x = 2m+ 3, so the x-coordinate is 2m + 3.

What is the y-ccordinate?

Answer 6

x?

Answer 7

no.

y = f(x)...do you know what that means?

Answer 8

That makes the equation a function?

Answer 9

Do you understand what "y = f(x)" means?

Answer 10

No.

Answer 11

well, that's part of the question. You have to go back to understand what "y = f(x)" means; then you will be able to do this question.

Answer 12

The best thing is to restudy what a function is, and what y = f(x) means. You can post a new question here from an earlier lesson on functions.

Answer 13

@amistre64 Can you please walk me through this question?

Answer 14

@jim_thompson5910 Can you help me?

Answer 15

y = f(x) ... given

y = f(2m+3) ... replace x with 2m+3 (since x = 2m+3)


So we know that x = 2m+3 and y = f(2m+3)


which means what?

Answer 16

Which means that we'll get the x coordinate(s) by doing the x = given equation, and that we'll get the y coordinate(s) by doing the y = given equation?

Answer 17

exactly

Answer 18

well replace "equation" with "expression" and you're more correct

so what is the answer?

Answer 19

d?

Answer 20

good
