Explanation / Answer

s(x) = 2x + 9

s(x + h) = 2(x + h) + 9 ---> 2x + 2h + 9

Now, we are finding s(x+h) - s(x) / h expression...

((2x + 2h + 9) - (2x + 9)) / h

Opening brackets :

(2x + 2h + 9 - 2x - 9) / h

2h/h

2

Now, to that apply lim h ---> 0

Since there is no h term present, applying the limit makes no difference
