Why can't X be zero in the reciprocal function?

• Because it would result in a negative number

• Because it would result in a division by zero

• Because it would result in a complex number

• Because it would result in an undefined number

Why does the reciprocal function have a vertical asymptote at x = 0?

• Because the function is negative at x = 0

• Because the function is infinite at x = 0

• Because the function is zero at x = 0

• Because the function is undefined at x = 0
