I've just started studying Integrals and Definite Integrals, and got stuck. I tried applying the Power Rule, but the result doesn't match with the answers.
Here is the question:
. . .\(\displaystyle \mbox{(9) Let }\, f(x)\, =\, \big| \, x^2\, -\, 1\, \big| .\, \mbox{ Then }\, f(0)\, =\, \boxed{\,(1)\,}\, \mbox{ and }\, \)\(\displaystyle \displaystyle \int_0^2\, f(x)\, dx\, =\, \boxed{\, (2)\,}.\)
And the answers are:
1-) 1
2-) 2
How can I solve this?
Thanks in advance.
