B. Yes, because it passes the vertical line test.
Rewrite in standard form and use the form to find the vertex.
(1, 5)
(x - 1)^2 + 5
To check if a relation is a function, given a mapping diagram of the relation, use the following criterion: If each input has only one line connected to it, then the outputs are a function of the inputs.
The answer to the problem is x=7. Here is the work:
<span>2(p + 1) = 24
Use distributive property
2p+2=24
Subtract 2 from both sides
2p=22
Divide 2 on both sides
Final Answer: p=11</span>
