You can put this solution on YOUR website! Suppose that for a function f, the equation f (x) = 0 has no real-number solution. Which of the following statements MUST be true?
a. f has no x-intercept:: true.
b. f has no y-intercept:: no, could be a parabola above x-axis and opening up
c. f is an invertible function:: no, could be a horizontal line.
d. The graph of f is a horizontal line:: no, could be a parabola above x-axis
and opening up.
