Answer:

D:  (-3, 0, 2, 9)

R: (4, 6, 7)

This relationship is a function as there are no two input that have the same output.

Step-by-step explanation:

This relationship is a function as there are no two input that have the same output.

The range is the second output (y-value) which is (4, 6, 7).

The domain is the first element (x-value) of a relation or function which is (-3, 0, 2, 9)

Hope this helps!

Which of the following is the equation of the quadratic function below?
exis [7]

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.
