Question

Please solve these question step by step ​

Answer 1

Answer:

1) 3x+5

ans. diff. w.r.t. x

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

=3(1) + 0

= 3

2) x^-2

ans. diff. w.r.t. x

dy/dx = d/dx (x^-2)

= -2x

4) 1÷ (X+2)

ans. dy/dx = d/dx [1÷( X+2)]

= 1 ÷ 1+0

= 1÷1

= 1

hope this helps you ( I've problem in solving 3 one )

plz mark it as Brilliant answer
