Atrue-false test contains 18 questions. in how many different ways can the 18- question test be answered?

Well if there are 18 questions and only 2 types of answers to give that would be 18 times two = 36 right?

I think in only one way by writing TRUE or FALSE...

Idon't see any graph, however the graph of the function : f(x) = x²-2x+3 is a parabola: 1) open upward (since a> 0)2) it intersects y-axis in 3 (y=3)3) its axis of symmetry is x = +1 ( -b/2a)4) it's minimum is y = -2, so its vertex is (1,-2)5) it doesn't intersect the x-axis since discriminant < 0
