Answer:
The new lower limit of integration is 26 and the new upper limit of integration is 82.
Step-by-step explanation:
If the substitution for the definite integral from 5 to 9 is given by:
[tex]u=x^2+1[/tex]
Then the new limits of integration are:
New lower limit:
Evaluate 5 in u:
[tex]u=(5)^2+1=25+1=26[/tex]
New upper limit.
Evaluate 9 in u:
[tex]u=(9)^2+1=81+1=82[/tex]
