Differentiate. F(x) = (x3 - 3)2/3 2x f'(x) - 3 8 O f'(x) = 3 8 2x2 f'(x) 3 VX3 -8 f(x) 3 V3-8​
oee [108]

Answer:

f'(x) =   \frac{2{x}^{2}}{ \sqrt[3]{( {x}^{3}  - 8) } }

Step-by-step explanation:

f(x) = ( {x}^{3}  - 8)^{ \frac{2}{3} }  \\  \\ f'(x) =  \frac{2}{3} ( {x}^{3}  - 8)^{ \frac{2}{3} - 1 } (3 {x}^{2}  - 0) \\  \\ f'(x) =  \frac{2}{3} ( {x}^{3}  - 8)^{ \frac{2 - 3}{3}  }  \times 3 {x}^{2} \\  \\ f'(x) =  2{x}^{2}( {x}^{3}  - 8)^{ \frac{ - 1}{3}  } \\  \\ f'(x) =   \frac{2{x}^{2}}{( {x}^{3}  - 8)^{ \frac{ 1}{3}  } } \\  \\ \huge \red{ \boxed{ f'(x) =   \frac{2{x}^{2}}{ \sqrt[3]{( {x}^{3}  - 8) } } }}

Given: -1/2 x > 6. Choose the solution set. {x | x R, x > -12} {x | x R, x < -12} {x | x R, x > -3} {x | x R, x <
Alex787 [66]

Answer:

{x|x ∈ R, x < - 12 }

Step-by-step explanation:

given - \frac{1}{2} x > 6

multiply both sides by - 2

Remembering to reverse the inequality symbol as a consequence of multiplying by a negative value

x < - 12 ← reverse symbol

{ x | x ∈ R, x < - 12 } ← solution set
