Question

Differentiate the following w.r.t x
(i) 3x + 5
( ii) x-2

Answer 1

(i) d(3x + 5)/dx = 3dx/dx + d5/dx = 3x1 + 0 = 3

(ii) d(x - 2)/dx = dx/dx - d2/dx = 1 - 0 = 1

please mark me as brainliest

Answer 2

Answer:

i)3

ii)1

Explanation:

i)d/dx(3x+5)=d/dx(3x)+d/dx(5)

=3(d/dx(x))+0

=3

ii)d/dx(x-2)=d/dx(x)-d/dx(2)

=1-0

=1
