A horizontal line meets the graph of the function y=f(x) in two points is f one one?

Explanation

To determine if the function \( f(x) \) is one-one (injective), we can use the horizontal line test. Here’s the step-by-step solution:

### Step 1: Understand the Horizontal Line Test
The horizontal line test states that if any horizontal line intersects the graph of a function more than once, then the function is not one-one.

### Step 2: Visualize the Function
Imagine the graph of the function \( y = f(x) \). For this problem, we assume that a horizontal line intersects this graph at two distinct points.
