I NEED MORE HELP FOR PART C$.$ Use the graph of the function f$($x$)=$x$^(2)-1$ to answer the following questions:

$($a$)$ Find $\backslash$int$\_(-\backslash$sqrt$(3))^(\backslash$sqrt$(3))$ x$^(2)-1$dx$(1$x$^(3))/(3)-$x$|\_(-\backslash$sqrt$(3))^(\backslash$sqrt$(3))(((\backslash$sqrt$(3))^(3))/(3)-\backslash$sqrt$(3))-(((-\backslash$sqrt$(3))^(3))/(3)-(-\backslash$sqrt$(3)))=0$

$($b$)$ Find $\backslash$int$\_(-1)^1$ x$^(2)-1$dx$($x$^(3))/(3)-$x$|\_(-1)^(1)((1^(3))/(3)-1)-(((-1)^(3))/(3)-(-1))=-(2)/(3)-(2)/(3)=-(4)/(3)$

$($c$)$ Find $\backslash$int$\_(-\backslash$sqrt$(3))^(\backslash$sqrt$(3))|$x$^(2)-1|$dx:$\backslash$int$\_(-\backslash$sqrt$(3))^(-1)$ x$^(2)-1$dx$+\backslash$int$\_(-1)^1$ x$^(2)-1$dx$+\backslash$int$\_1^(\backslash$sqrt$(3))$ x$^(2)-1$dx

$-(4)/(3)$x$\_(2)=(8)/(3)$
