f%28x%29=4x%5E3+-+3x%5E2+-+x+%2B+2 Start with the given equation.


f%281%29=4%281%29%5E3+-+3%281%29%5E2+-+1+%2B+2 Plug in x=1.


f%281%29=4%281%29-3%281%29%5E2-1%2B2 Cube 1 to get 1.


f%281%29=4%281%29-3%281%29-1%2B2 Square 1 to get 1.


f%281%29=4-3%281%29-1%2B2 Multiply 4 and 1 to get 4.


f%281%29=4-3-1%2B2 Multiply -3 and 1 to get -3.


f%281%29=2 Combine like terms.
