Question

the graph of x=p(y) is given below for some polynomial p(y) find the number of zeroes of p(y)​

Answer 1

Answer:

Step-by-step explanation:

We have to find the no of zeros of p(y).so we can count the no of cut on y axis that is 4...

So the answer is 4

Answer 2

The number of zeroes of p(y) is 4

Given : The graph of x = p(y) for some polynomial p(y)

To find : The number of zeroes of p(y)

Solution :

Step 1 of 2 :

Find the number of points where the graph of x = p(y) cuts y axis

We observe that the graph of x = p(y) cuts y axis at four points

Step 2 of 2 :

Find number of zeroes of p(y)

We know that for a polynomial p(y) the zeroes are the the points where the graph cuts y axis

More precisely the y - coordinate of the points of intersection with y axis is the zeroes of the polynomial p(y).

Since the graph of x = p(y) cuts y axis at four points

Hence the number of zeroes of x = p(y) is 4
