Determine whether the relation is a Function using the Vertical Line test.1. y = x² - 2x + 1description: A U-Shaped Parabola Opens upward and passes through Points like (0,1),(1,0), and (2,1).
Answer (1)
To check if y = x² - 2x + 1 is a function, use the Vertical Line Test. If a vertical line crosses the graph only once at any x-value, then it is a function. The given parabola is U-shaped and opens upward. A vertical line will only cross it once at every x-value. So, it is a function.
