Question

f(x)=12/(x2-3x-108)

Answer 1

what you wanna do with that equation?

Answer 2

find the domain of f then write it in interval notation

Answer 3

you can start by factoring the denominator of
f(x)=12/(x2-3x-108)

f(x)=12/(x-12)(x+9)

Answer 4

for R (real),now we know that x is not = 12 and -9

Answer 5

so the answer must be
set of real number R except x=12 and x=-9
or write them in
\[{ x/x \epsilon R, x \neq -9, and, x \neq 12 }\]
