Consider the following integral. $9$ e$1$xx$2$dx$1$ Find a substitution to rewrite the integrand as $$eu du$.$ u$=$ du$=$dx Indicate how the limits of integration should be adjusted in order to perform the integration with respect to u$.($Hint: If an integration substitution results in $[$a$,$ b$]$ with a $>$ b$,$ the limits of integration must appear in that order.$)[1,9]$ Evaluate the given definite integral.
