Question
If f (x) = x2 − 4x + 10 and c is a positive integer less than 5, what is one possible value of f (c) ?
The correct answer is: 6
f(x) = x2 – 4x + 10
c = less than 5
c = 4 ⇒ f(4) = 16 – 16 + 10 = 10
c = 3 ⇒ f(3) = 9 – 12 + 10 = 7
c = 2 ⇒ f(2) = 22 – 8 + 10 = 6
c = 1 ⇒ f(1) = 1 – 4 + 10 = 7
possible values of f(1) = (6, 7, 10)
