Question

Determine the point(s) at which the given function f(x) is continuous. Describe the set of x-values where the function is continuous, using interval notation.

f(x)=13/x-15 - 5x

Answer 1

it will be continuous for all numbers, except where the denominator is zero

Answer 2

how?

Answer 3

i can't really read what you wrote, but whatever the denominator is, set it equal to zero and solve
like for example
\[f(x)=\frac{x}{x-1}+6\] is continuous at all numbers except \(1\) because if \(x=1\) then the denominator would be 0

Answer 4

o ok now i understand.
