The function $y=f(x)$ is given by the figure.

$v$

$A(x)={\displaystyle \underset{0}{\overset{x}{}}}f(t)dt,B(x)={\displaystyle \underset{2}{\overset{x}{}}}f(t)dt$

Find formulas for $A(x)$ and $B(x)$ valid on $4,5.$

$($Express numbers in exact form. Use symbolic notation and fractions where needed.$)$

$A(x)=2$

Incorrect Answer

$B(x)=x-2$
