Step-by-step explanation:
Normally, in a problem like this one, you'd be given a couple of x-values at which to evaluate the function. Since you didn't do that here, I'll just invent a few: {-1, 0, 7, 11}.
For x = - 1: substitute - 1 for x in f (x) = x^2 - 3x+2: f (-1) = (-1) ^2 - 3 (-1) + 2 = 6:
f (-1) = 6
Next:
f (0) = 0 - 0 + 2 = 2, so f (0) = 2
For x = 7, substitute 7 for x in f (x) = x^2 - 3x+2: f (7) = 49 - 21 + 2 = 30 = f (7)
For x = 11, f (11) = 121 - 33 + 2 = 90 = f (11)
