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 1

Answer:

(2b, 2b + 7)

Step-by-step explanation:

Let's remember that an ordered pair has the value of x on it first coordinate and the value of f(x) (or we can call it "y") in the second one.

We already know that the value of x is 2b, let's see what's the value of f(2b):

We just need to replace the x with 2b:

f(2b) = 2b + 7

Therefore, the ordered pair for the point on the graph when x = 2b is (2b, 2b + 7)

Answer 2

Answer:

(2b, 2b + 7)

Step-by-step explanation:

y=f(x) = x +7

x= 2b

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

(2b, 2b + 7)
