Question

for which value of x is f(x)=1 divided by 27-3^x undefined?

Answer 1

That would meant that 27 - 3^x = 0, because when the denominator = 0, the whole thing is undefined...now try to solve for it! ^^

Answer 2

is it 3?

Answer 3

Yup! xD

Answer 4

would i write that x and a equal sign with a slash through it than 3 for x is not equal to 3?

Answer 5

it's undefined when x = 3
