# C1 Graph question watch

1. y = 1/ x^

When y = 0

what does x = ?
2. (Original post by IShouldBeRevising_)
y = 1/ x^

When y = 0

what does x = ?
It doesn't it is undefined.
3. (Original post by IShouldBeRevising_)
y = 1/ x^

When y = 0

what does x = ?
as y tends towards 0, x tends towards infinity
4. (Original post by natninja)
as y tends towards 0, x tends towards infinity
so both the y - axis and x - axis are asymptotes?

This is what I thought but in the mark scheme the graph is touching the x - axis

yes, both axes are asymptotic, sometimes the mark scheme's graphs are not well drawn... especially for the Solomon practice papers
