If d d x f (x)=4 x^3- 3 x^4 such that f (2)=0 , then f (x) is equal to
Options
- Ax^4+ 1 x^3 + 129 8
- Bx^4+ 1 x^3 - 129 8
- Cx^3+ 1 x^4 + 129 8
- Dx^3+ 1 x^4 - 129 8
Correct answer
B. x^4+ 1 x^3 - 129 8
Step-by-step solution
Given that f ^ (x)=4 x^3-3 x⁻⁴ array ll & f (x)= (4 x^3-3 x⁻⁴ ) d x & f (x)=x^4+ 1 x^3 + c array Given that f (2)=0 array ll & 16+ 1 8 +c=0 & c= -129 8 & f (x)=x^4+ 1 x^3 - 129 8 array
