Answer:
2,3&5
Step-by-step explanation:
y-intercept is the y-coordinates when x = 0,
Rewrite all the equations:
1. x² - 2x + 13
2. x² - 8x + 12
3. x² - 7x + 12
4. x² - 7x + 6
5. x² - 4x + 12
6. x² + 7x + 10
if the form of the quadratic equation is ax² + bx + c, c is the y-intercept of the function, thus 2,3&5 got the same y-intercept as the function f(x) = x² - 7x +12, which is 12.
