b=9:15
Step-by-step explanation:
The following answer would be D because I’m guessing and I need the answers too sorry
Answer:
A. y = x² - 9x + 18
Step-by-step explanation:
The key thing to look for in this graph is the <u>y-intercept</u> (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:
<em>y = ax² + bx + <u>c</u></em>
'<em>c</em>' tells you what the y-intercept is.
The choices with positive y-intercept are <u>A</u> and <u>B</u>.
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.
