Question

Let the function f be defined by the equation y = f(x), where x and f(x) are real numbers. Find the domain of the function.

Answer 1

\[f(x)=x+3 \over x-13\]

Answer 2

all real x, \[x \neq13\]

Answer 3

these are my choices for the answer
a.(-[\infty\], 13) ∪ (13,[\infty\] )
b. (-[\infty\], -13) ∪ (13,[\infty\] )
c. (-[\infty\],[\infty\] )
d. (-[\infty\], 0] ∪ (13,[\infty\] )
e. (- [\infty\] , -13] ∪ [13,[\infty\] )

Answer 4

suppose to be [\infty\] infinity sign

Answer 5

then it would be "a"

that includes all points except x=13

Answer 6

thanks that where i thought you where going with it but was not sure..
