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

For this case we have the following function:
 F (x) = 1 / x
 We observe that the function is not defined when the denominator is equal to zero, or equivalently:
 x = 0
 The function tends to infinity when x takes positive values close to zero.
 The function tends to minus infinity when x takes negative values close to zero.
 Answer:
 A - Either a very large positive or very large negative number
