Question

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

A. ( 2b, 2b+7)
B. ( 2b, x + 7)
C.( x, x + 7 )
D. (x, 2b + 7)

Answer 1

I hope this helps you

Answer 2

A. (x,y)=(2b,2b+7)

Explanation:

We have the function
`f(x)=x+7` and we have to replace x=2b in the function.

Observation:
`y=f(x)`

This means:

`f(x)=x+7\\f(2b)=2b+7\\y=2b+7`

Then when x=2b, y=2b+7. The ordered pair corresponding to x=2b is

(x,y)=(2b,2b+7)
