Answer:
9/4
Step-by-step explanation:
The quadratic function can be rearranged to look like this:
x^2-3x-1=0
Now we see that the constant b is equal to -3. Using the hint, we find:
(-3/2)^2=9/4

Answer:
(3, -4)
Step-by-step explanation:
The correct equation is:

From the list of given points, we have to identify which point lies on the graph. This can be done by using the value of x-coordinates from the given points and see if they result in the corresponding y-coordinate:
For point (1, 4)
 , This is not equal to 4, so it does not lie on the graph of given function.
, This is not equal to 4, so it does not lie on the graph of given function.
For point (3, -4)
 , The answer ans corresponding y-coordinate are the same. This means, (3, -4) point lies on the graph of given function.
, The answer ans corresponding y-coordinate are the same. This means, (3, -4) point lies on the graph of given function.
Likewise, checking for 3rd and 4th point we find out that they do not lie on the graph.
So the correct answer is (3, -4)
