If the derivative of y = k(x) equals 2 when x = 1, what is the derivative of(adsbygoogle = window.adsbygoogle || []).push({});

(a) k(2x) when x = 1/2?

(b) k(x+1) when x = 0?

(c) k ((1/4)x) when x = 4?

Here is my work:

k'(1) = 2

(a) k'(2x) = ?

k'(2(1/2)) = ?

k'(1) = 2

(b) k'(x+1) = ?

k'(0+1) = ?

k'(1) = 2

(c) k'((1/4)x) = ?

k'((1/4)(4)) = ?

k'(1) = 2

Is the answer for every question 2?

I just find it strange that this question would be that easy, so naturally I think I approached it incorrectly.

Please tell me if it is correct.

Thanks.
