Step-by-step explanation:
I think so I might not be right but I'm sure it's c
18 / 2 = 9 || 9 x 3 = 27. Therefore, 27 students are registered in Bob’s class.
Step-by-step explanation:
You want the to find the value of k such that the y coordinate of the vertex is 0.
0=x2−6x+k
The x coordinate, h, of the vertex is found, using the following equation:
h=−b2a
h=−−62(1)=3
Evaluate at x = 3:
0=32−6(3)+k
k=9
You know that
.
Use the property
to state that

Then the expression
is equivalent to

Answer: correct choice is A.
If the function is y=6
It's a constant
For any value of input the output will be equal to 6
therefore
the Outputs when the Inputs is 1,7,-3,and -5 is 6
