11. Multiple Choice

Suppose that a function f has no x-intercepts. Which of the following statements MUST be true? The graph of f has no points whose x-coordinate is 0. f is an invertible function. The equation f(x) = 0 has no real-number solution. The graph of f is a horizontal line.

Solution

f has no x-intercepts.
As in, the function never meets the x-axis.

This has to mean that f(x) = 0 has no solutions....

So, option C
