Q. For the following equation, find f(x) f^{\prime}(x) .\newlinef(x)=4x5+8x44x3x26x f(x)=-4 x^{5}+8 x^{4}-4 x^{3}-x^{2}-6 x \newlineAnswer: f(x)= f^{\prime}(x)=
  1. Apply Power Rule: To find the derivative f(x)f'(x) of the function f(x)=4x5+8x44x3x26xf(x) = -4x^{5} + 8x^{4} - 4x^{3} - x^{2} - 6x, we will apply the power rule to each term individually. The power rule states that the derivative of xnx^n with respect to xx is nxn1n*x^{n-1}.
  2. Derivative of 4x5-4x^{5}: First, we find the derivative of the term 4x5-4x^{5}. Using the power rule, we get:\newlineddx(4x5)=4×5×x51=20x4\frac{d}{dx}(-4x^{5}) = -4 \times 5 \times x^{5-1} = -20x^{4}.
  3. Derivative of 8x48x^{4}: Next, we find the derivative of the term 8x48x^{4}. Using the power rule, we get:\newline rac{d}{dx}(8x^{4}) = 8 \cdot 4 \cdot x^{4-1} = 32x^{3}.
  4. Derivative of 4x3-4x^{3}: Now, we find the derivative of the term 4x3-4x^{3}. Using the power rule, we get:\newlineddx(4x3)=4×3×x31=12x2\frac{d}{dx}(-4x^{3}) = -4 \times 3 \times x^{3-1} = -12x^{2}.
  5. Derivative of x2-x^{2}: Then, we find the derivative of the term x2-x^{2}. Using the power rule, we get:\newlineddx(x2)=1×2×x21=2x\frac{d}{dx}(-x^{2}) = -1 \times 2 \times x^{2-1} = -2x.
  6. Derivative of 6x-6x: Finally, we find the derivative of the term 6x-6x. Since this is a linear term, its derivative is simply the coefficient of xx:ddx(6x)=6.\frac{d}{dx}(-6x) = -6.
  7. Combine Derivatives: Combining all the derivatives we've calculated, we get the derivative of the entire function f(x)f(x):f(x)=20x4+32x312x22x6.f^{\prime}(x) = -20x^{4} + 32x^{3} - 12x^{2} - 2x - 6.
