If f(0) = 0, f(1) = 2, f(2) = 9, and ax^2+bx+c=0, what is the value of f(3)?

Sub in x = 0     will show   c = 0

 

now sub in x = 1    to get   a+b = 2

  now sub in x = 2  to get   4a + 2b = 9             Solve red equations to get    a = 2.5      b = -.5

 

2.5 x2  - .5 x  + 0 = 0      now sub in x = 3   to find your answer
