Find the value of 6+x when x = 15.

Step-by-step explanation:

Given the function f (x) = 6+x

F (x) is dependent on x,

When x=1

f (x) = 6+x

f (x) = 6+1,

f (x) = 7

When x=2

f (x) = 6+x

f (x) = 6+2

f (x) = 8.

This will continue like this till we get to x=15

So when x=15

We will substitute x=15 into the function f (x)

f (x) = 6+x

f (x) = 6+15

f (x) = 21

Then, the answer is 21.

Answer: 17

Step-by-step explanation:

To solve 6+x when x = 15,

Step 1: Substitute 15 into x

Step 2: Sum 6 and 15

6+15 = 17.
