If f ( x ) = 20 , find f ' ( 5 ) .

Question

any help would be amazing thanks

Answer 1

Hi,

If f ( x ) = 20 it means f(x) is a constant function and slope is ZERO that the same meaning of derivative at any point!!!

Now, f ' ( 5 ) = slope = 0

I hope it is useful,

Answer 2

If f(x) = 20 f is a constant function with slope of 0 (zero).

Therefore the slope at 5, f'(5), is zero.

f'(5) = 0
