Question

identify the excluded value.
f(x)=5/x

Answer 1

what value of x makes the denominator 0?

Answer 2

5?

Answer 3

nope, try again

what is the denominator?

Answer 4

the denominator is the bottom number of the fraction, so if i used 0, would that make it undefined or would it make it 0? or is that the same thing?

Answer 5

when you divide by 0, the answer is undefined

so, when you put in x = 0, the function is undefined, so x = 0 is the excluded value

Answer 6
