f%282%29=2t%5E2-4t-1 Start with the given function.


f%282%29=2%282%29%5E2-4%282%29-1 Plug in t=2.


f%282%29=2%284%29-4%282%29-1 Square 2 to get 4.


f%282%29=8-4%282%29-1 Multiply 2 and 4 to get 8.


f%282%29=8-8-1 Multiply -4 and 2 to get -8.


f%282%29=-1 Combine like terms.


So the answer is f%282%29=-1
