Find f(a), f(a + h), and the difference quotient f(a + h) − f(a) / h , where h ≠ 0. f(x) = 6

Question

f(a) =

Incorrect: Your answer is incorrect.
f(a + h) =

Incorrect: Your answer is incorrect.
f(a + h) − f(a)
h
=

 

I need help determining what the answer will be when plugging these numbers in.

Answer 1

Since f(x) = 6, f(x) = 6 for any value of x.

 

So, f(a+h) = 6 and f(a) = 6

 

Therefore, [f(a+h) - f(a)] / h = (6-6) / h = 0
