1) f(x) =5x + 9;f(2)

Answer 1

Do you know what a derivative is?

Answer 2

You're in the college of engineering, there is a grammatical mistake in the document (loose), and you can't answer my question?

I hate modern education...

Answer 3

yeah i agree u

Answer 4

any idea of solution

Answer 5

I have a better idea about solving it.

Answer 6

tell me

Answer 7

You're given\[f(x)=5x+9,\]and you want to find \(f'(x)\). To do that, evaluate\[f'(x)=\lim_{h\to0}\frac{[5(x+h)+9]-(5x+9)}{h}.\]

Answer 8

ok and the answer is

Answer 9

Work it out yourself, Mr. Engineer.

Answer 10
