Complete the given sentence. (Enter your answers as a comma-separated list. If there is no such point, enter NONE.)
The closed-form function 
f(x) =  7 /x^2 − 16
 is continuous for all x except x =

anonymous · Answer

except when x^2-16 =0 ..
x^2=16  x= plus or minus 4

anonymous · Answer

the answer is x = 0 because as x approaches 0, f(x) approaches infinity

anonymous · Answer

yeah i guess it depends if it's 7/(x^2-16) or (7/x^2-)16 i'm guessing they'd probably ask you the first one.. or else why would the square work out nicely :P

anonymous · Answer

well the way she typed it, the answer is x=0
