Answer:
A. y = x² - 9x + 18
Step-by-step explanation:
The key thing to look for in this graph is the y-intercept (where the graph will hit the y-axis).
We can't see exactly where y-intercept is, but we know it is a positive number.
In a standard form quadratic equation:
y = ax² + bx + c
'c' tells you what the y-intercept is.
The choices with positive y-intercept are A and B.
Again, we can't see exactly where y-intercept is, but we know it is not 1.
y = x² - 9x + 18
has a positive y-intercept that is not 1,
thus the answer is A.
