Question

Evaluate f(x) = x^2 -3x+2

Answer 1

Answer:

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)
