f%28x%29=1x%5E3%2B1x%5E2-1 Start with the given function


f%281%29=1%281%29%5E3%2B1%281%29%5E2-1 Plug in x=1


f%281%29=1%2A1%2B1%2A1%5E2-1 Raise 1 to the 3rd power to get 1


f%281%29=1%2B1%5E2-1 Multiply 1 and 1 to get 1


f%281%29=1%2B1-1 Raise 1 to the 2nd power to get 1


f%281%29=1%2B1-1 Multiply 1 and 1 to get 1


f%281%29=2-1 Add 1 and 1 to get 2


f%281%29=1 Subtract 1 from 2 to get 1
