Question

How do I do this and what is the answer?

For the function f(x) = x + 5, what is the ordered pair for the point on the graph when x = 4w?

A) (4w, x + 5)
B) (4w, 4w + 5)
C) (x, x + 5)
D) (x, 4w + 5)

Answer 1

Take x + 5, and replace x with 4w.
What do you get?

Answer 2

4w + 5?

Answer 3

Exactly.
Since f(4w) = 4w + 5, that means the ordered pair has 4w for x and 4w + 5 for y.
Which choice has that?

Answer 4

A?

Answer 6

do you know? @Vocaloid

Answer 7

A is (4w, x + 5)
We have 4w for x but 4w + 5 for y, not x + 5 for y.

Answer 8

oh is it B?
