Question

For the function F(x) = 1/x, whose graph is shown below, what is the relative value of F(x) when the value of x is close to zero?

A - Either a very large positive or very large negative number
B.A very small positive number
C. Only a very large positive number
D.Only a very large negative number
E.Either a very small positive or very small negative number

Answer 1

Well think about it. If you divide by something less than 1, your number gets bigger.


`2 / 0.1 = 20`

Same thing when it's negative, except now the answer is negative. So, if x gets really close to 0, it will be very big, or a big negative number. Remember, "getting close to 0" could mean from the negative side just as well from the positive.
