Q. For the following equation, find f(x) f^{\prime}(x) .\newlinef(x)=6x59x4+x3+6 f(x)=-6 x^{5}-9 x^{4}+x^{3}+6 \newlineAnswer: f(x)= f^{\prime}(x)=
  1. Apply Power Rule: To find the derivative of the function f(x)=6x59x4+x3+6f(x) = -6x^{5} - 9x^{4} + x^{3} + 6, we will apply the power rule to each term separately. The power rule states that the derivative of xnx^n with respect to xx is nx(n1)n\cdot x^{(n-1)}.
  2. Derivative of 6x5-6x^{5}: First, we find the derivative of the term 6x5-6x^{5}. Using the power rule, we get:\newlineddx(6x5)=6×5×x51=30x4\frac{d}{dx}(-6x^{5}) = -6 \times 5 \times x^{5-1} = -30x^{4}.
  3. Derivative of 9x4-9x^{4}: Next, we find the derivative of the term 9x4-9x^{4}. Again, using the power rule, we get:\newlineddx(9x4)=9×4×x41=36x3\frac{d}{dx}(-9x^{4}) = -9 \times 4 \times x^{4-1} = -36x^{3}.
  4. Derivative of x3x^{3}: Then, we find the derivative of the term x3x^{3}. Using the power rule, we get:\newline(ddx)(x3)=3×x(31)=3x2.(\frac{d}{dx})(x^{3}) = 3 \times x^{(3-1)} = 3x^{2}.
  5. Derivative of constant: Finally, the derivative of a constant is zero, so the derivative of the term +6+6 is:\newlineddx(6)=0\frac{d}{dx}(6) = 0.
  6. Combine all derivatives: Now, we combine the derivatives of all terms to find the derivative of the entire function f(x)f(x):f(x)=30x436x3+3x2+0.f'(x) = -30x^{4} - 36x^{3} + 3x^{2} + 0.
