Remember that squaring something is just multiplying that number by itself.
Answer:
up, down
Step-by-step explanation:
It is an even-degree polynomial. Therefore, the start of domain is the opposite the end of domain.
Meaning if the graph starts by decreasing, the graph will end by increasing.
Because the coefficient of highest degree is in negative. Therefore, the graph starts from negative infinity, increasing. The graph will end in positive infinity but decreasing.
Therefore, the answer is first choice.
Answer:
- 132°
Step-by-step explanation:

<h3>Given </h3>- JM = 27, ML = 16, JL = 46, NK = 15, m∠KLM = 48°, m∠JKM = 78°, and m∠MJL = 22°
- m∠JKL
<u>JKLM is a parallelogram and therefore has equal opposite angles:</u>
- ∠JKL = ∠JML and ∠KJM = ∠KLM
<u>Sum of all four is 360°:</u>
- 2m∠JKL + 2m∠KLM = 360°
- m∠JKL + m∠KLM = 180°
- m∠JKL + 48° = 180°
- m∠JKL = 180° - 48°
- m ∠JKL = 132°
