Hi everyone,

I also called to complain, however they referred to the state definition
of a root as found on the glossary at:
http://emsc32.nysed.gov/ciai/mst/math/glossary/home.html

Specifically, here is the root definition:

root of an equation (A) (A2T) A solution to an equation of the form
f(x) = 0.

Example: A root of the equation y = 6x - 18 is 3 because when 3 is
substituted in for x, the value of y = 0.

Example: The roots of are and . The equation is true if we
substitute either or into the equation.

Even though this definition is pretty clear as to the need for the roots
to be stated as a solution, the wording of the question is very

Also, while we were chatting, she also stated that any intercept is the
value as well, and not the coordinate. For example, the y-intercept of
y=3x+5 is 5, and not (0,5). Who knows, maybe something like this might
appear in the future, where semantics between definitions are used to
catch students!

Have a great weekend everyone!

We strongly disagree, but were told by the state that it had to be x
=-4 and x =2. ii argued that students displayed understanding by
locating the points on the graph.

Any thoughts about #34 on yesterday's algebra exam? Anyone
agre/disagree with the rubric not allowing full credit if the student
lists the coordinates instead of writing x =-4 and x =2?
