Answer:
<h2>
        y = x² - 1</h2>
Step-by-step explanation:
y = -1 for x = 0 {point(0, -1)} means -1 at the end of formula
If we add 1 to y-coordinate of  every given point we get the squares of x-coordinate:
(1, 0):   1² - 1 = 0
(2, 3):   2² - 1 = 4 - 1 = 3
(3, 8):   3² - 1 = 9 - 1 = 8
(4, 15):   4² - 1 = 16 - 1 = 15
So for any x:
(x, y)   y = x² - 1
