**Description :** Why can a function have multiple x-intercepts but only one y-intercept?

**Last Answer :** It can, but only if the line drawn is a curve. ---------------------------------------------------------------------------------- The function is a polynomial of the form: y = f(x) = ... value, eg y = xÂ² has y = 4 for x = Â 2). Thus there will only be one y value for x = 0, ie only one y-intecept.
