# One last question

Calculus Level 4

Let's define a differential equation:

$\displaystyle \dfrac{d^{2}y}{dx^{2}} - \dfrac{dy}{dx}+y=x$

with its initial conditions as $$\displaystyle y(1)=1 , y'(1)=0$$ .

If $$\displaystyle y=f(x)$$ is the solution of the given $$DE$$, evaluate $$\displaystyle f(1.21)$$ .
