Answer:
100f(x); one x-intercept
Step-by-step explanation:
25x² - 10x + 1 → [5x - 1]²; set this Binomial equal to 0, and you get your x-intercept of [⅕, 0], which is also your <em>vertex</em><em>.</em>
Now, for your discriminant, you have to use all the values of <em>c</em><em>,</em><em> </em><em>b</em><em>,</em><em> </em>and <em>a</em><em> </em>to find it [b² - 4ac]:
- 0 > b² - 4ac → No real solutions
- 0 < b² - 4ac → Two solutions
- 0 = b² - 4ac → One solution
