a)

g%28x%29=3x%5E2%2B2x%2B3

g%28-1%29=3%28-1%29%5E2%2B2%28-1%29%2B3

g%28-1%29=3%281%29%2B2%28-1%29%2B3

g%28-1%29=3-2%2B3

g%28-1%29=4

-------------------------------------------------------

b)

g%28p%2B2%29=3%28p%2B2%29%5E2%2B2%28p%2B2%29%2B3

g%28p%2B2%29=3%28p%5E2%2B4p%2B4%29%2B2%28p%2B2%29%2B3

g%28p%2B2%29=3p%5E2%2B12p%2B12%2B2p%2B4%2B3

g%28p%2B2%29=3p%5E2%2B14p%2B19
