Hi! Kindly answer this :)) thankyou!

Determine the a) roots, b) vertex, and c) domain and range of the given functions.
Illustrate its graph.
1. f(x) = x² – 8x + 15
2. f(x) = x² – 6x + 8
3. f(x) = x² - 3x – 4
4. f(x) = x - 5x + 6
5. f(x) = 2x² + 5x + 3
6. f(x) = x² + x - 12
7. f(x) = x² + 2x – 3
8. f(x) = x² - 2x - 8
9. f(x) = 2x² - 3x + 1
10. f(x) = x² - 7x + 3
