Answer the question about the given function.
-Given the functi $$f ( x ) = - 6 x ^ { 2 } + 12 x - 9$$ , if x = 1, what is f(x)? What point is on the graph of f?
A) -3; (1, -3)
B) -3; (-3, 1)
C) -27; (1, -27)
D) -27; (-27, 1)

Quizplus · Accepted Answer

Substituting x = 1 into the function gives f(1) = -6(1)^2 + 12(1) - 9 = -6 + 12 - 9 = -3. Therefore, the point on the graph is (1, -3).
