If \(f(x)=x^4-x^3+7 x^2+14\), then what is the value of \(f^{\prime}(5)\) ?
- A 594
- B 549
- C 954
- D 495
Answer & Solution
Correct Answer
(D) 495
Step-by-step Solution
Detailed explanation
Since, \(f(x)=x^4-x^3+7 x^2+14\) Then, \(\quad f^{\prime}(x)=4 x^3-3 x^2+14 x\) \(\therefore \quad f^{\prime}(5)=500-75+70=495\)
