Differentiation Question 346

Question: If $ f(x)=3{e^{x^{2}}} $ ,then $ f’(x)-2xf(x)+\frac{1}{3}f(0)-f’(0)= $

Options:

A) 0

B) 1

C) $ \frac{7}{3}{e^{x^{2}}} $

D) None of these

Show Answer

Answer:

Correct Answer: B

Solution:

We have $ f(x)=3{e^{x^{2}}}. $ Differentiating w.r.t. x, we get $ f’(x)=6x{e^{x^{2}}} $ ;
$ \therefore f(0)=3 $ and $ f’(0)=0 $

Therefore $ f’(x)-2xf(x)+\frac{1}{3}f(0)-f’(0) $

$ =6x{e^{x^{2}}}-6x{e^{x^{2}}}+\frac{1}{3}(3)-0=1 $ .
