f%28x%29=-9x%2B2 Start with the given polynomial


f%28-2%29=-9%28-2%29%2B2 Plug in x=-2


f%28-2%29=18%2B2 Multiply -9 by -2 to get 18


f%28-2%29=20 Now combine like terms

f%28x%29=-9x%2B2 Start with the given polynomial


f%280%29=-9%280%29%2B2 Plug in x=0


f%280%29=0%2B2 Multiply 9 by 0 to get 0


f%280%29=2 Now combine like terms
