Question

How do you differentiate `f(x)=sqrt30`?

Answer 1

0

Explanation:

If we consider that for any constant ( a value that does not contain some variable) that comprises a function that is to be derived, that constant is eliminated in the derivation process.

As such, if we consider the general parabolic function;
`f(x)=ax^2+bx+c`

Its derivative may be expressed as;

`f'(x)=2ax+b`

Note that the constant has been eliminated from the expression - effectively giving it a value of zero.

Thus, graphically, as `f'(x)=sqrt30` is a straight line with a gradient of zero - its derivative across the domain `R` must also be zero.
