Question

For the function f(x) = x + 7, what is the ordered pair for the point on the graph when x = 2b?

(2b, 2b + 7)

(2b, x + 7)

(x, x + 7)

(x, 2b + 7)

Answer 2

Replace all x with 2b

f(x) = x + 7
f(2b) = 2b + 7

Answer 3

f(x) replaces y
so (x,f(x))

Answer 4

So the first one?

Answer 5

f(2b) = 2b + 7
because x=2b we replace each x with 2b
that leaves us with the the ordered pair (2b, 2b+7)

Answer 6

Thanks!

Answer 7

Don't worry about it. We're human. We're entitled to make mistakes sometimes. :)
