h%28x%29=2x%5E4-x%5E3%2B2x%5E2-4x-3 Start with the given function.


h%283%29=2%283%29%5E4-%283%29%5E3%2B2%283%29%5E2-4%283%29-3 Plug in x=3.


h%283%29=2%2881%29-%283%29%5E3%2B2%283%29%5E2-4%283%29-3 Raise 3 to the 4th power to get 81.


h%283%29=2%2881%29-1%2827%29%2B2%283%29%5E2-4%283%29-3 Cube 3 to get 27.


h%283%29=2%2881%29-1%2827%29%2B2%289%29-4%283%29-3 Square 3 to get 9.


h%283%29=162-1%2827%29%2B2%289%29-4%283%29-3 Multiply 2 and 81 to get 162.


h%283%29=162-27%2B2%289%29-4%283%29-3 Multiply -1 and 27 to get -27.


h%283%29=162-27%2B18-4%283%29-3 Multiply 2 and 9 to get 18.


h%283%29=162-27%2B18-12-3 Multiply -4 and 3 to get -12.


h%283%29=138 Combine like terms.
