यदि `f(x)=3x^(2)+15x+5` हो, तो `f(3.02)` का सन्निकट मान है:
`{:((a)47.66,(b)57.66),((c)67.66,(d)77.66):}`

Explanation

`f(x)=3x^(2)+15x+5`
`impliesf'(x)=6x+15`
माना `x=3` तथा `h=0.0.2`
माना `x=3` तथा `h=0.0.2`
अब `f(x+h)=f(x)+hf'(x)`
`impliesf(3.02)=f(3)+0.02xxf'(3)`
`=(3xx3^(2)+15xx3+5)+0.02xx(6xx3+15)=77+0.66=77.66`
