SAT question 5377d9cf (Nonlinear Functions)

Question

If f(x) = (x^2 - 6 x + 3)/(x - 1) , what is f(-1) ?

College Board · Accepted Answer

The correct answer is A. Choice A is correct. Substituting -1 for x in the equation that defines f gives f(-1) = ((-1)^2 - 6 × (-1) + 3)/(-1 - 1) . Simplifying the expressions in the numerator and denominator yields (1 + 6 + 3)/(-2) , which is equal to (10)/(-2) or -5 .
