Question

Hey, can somebody help me with this problem? :) _____
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)

_____
Thanks so much guys! <33

Answer 1

f(x) = x + 7

f(2b) = 2b + 7 ... replace each x with 2b (since x = 2b)

and you're done

so the ordered pair is (2b, 2b+7)

Answer 2

remember that y = f(x), so basically the input is x and the output is y or f(x)

so plugging in 2b in for x gives you 2b+7 out for y

Answer 3

Omg you're awesome thank-you so much <33

Answer 4

you're welcome
