Answer 2

Answer:

Step-by-step explanation:

Answer:-

• From the graph, we need to find zeroes of p(x)

What we need to do?

• p(x), so we need zeroes of x quadrant

Trick or solution:-

• The number of waves which touch x axis, is the required number of zeroes.
• Never, count the waves touching y axis.
• If it is written p(y), then y and not x axis.

Now, refer to attachment how I came up with the answer.

• I didn't count the wave touching y axis.
• So, the required answer is 2.

Hence, 2 zeroes are there in this polynomial.

Precautions:-

• 1 and 2 are the number of zeroes.
• Do not count them as the required zeroes.
• Also, zeroes are -3 and -1.
• The zeroes are on 3rd quadrant.
• The quadrants are counted Anti clockwise.
