Question

Va rog am nevoie de ajutor cât de repede posibil....

Answer 1

Răspuns:

1)

a) f'(x)=2x-5

d) f'(x)=2eˣ-1/x+1/(2√x)

g) f'(x) = 2(x-3) = 2x-6

h) f'(x) = 2(x+1)+3(x-2)² = 2x+2+3x²-12x+12 = 3x²-10x+14

i) f'(x) =2·1/2·1/√x+√2 = 1/√x+√2

k) f'(x) == -1/2·1/√x-3/x+x·3ˣ⁻¹ = -1/(2√x)-3/x+x·3ˣ⁻¹

l) f'(x) = 0-5·1/2·1/√x-5sin(x) = -5/(2√x)-5sin(x)

2)

a) f'(x) = eˣ + xeˣ

b) f'(x)=ln(x)+(x-2)/x

c) f'(x)=2x·2ˣ+x²·x·2ˣ⁻¹ = x·2ˣ⁺¹+x³·2ˣ⁻¹
