Which of the following is the equation of the quadratic function below?

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.

step-by-step explanation:

the options are kind of confusing. i can tell you what i see going on here when i look at the graph.

the class and exam medians are closely related, and it looks like the low outlier on the exam did pull the median lower. [tex][/tex]
