Question

shruti is very good in painting so she thought of exhibiting her paintings in which she want to display her latest painting which is in the form of graph of polynomial​

Answer 1

Answer:

I think is 30 square unit

Answer 2

(i) The number of zeroes of the polynomial represented by the graph is (c) 3.

• Since the graph intersects the x-axis at 3 points, the polynomial has 3 zeroes.

(ii) The sum of zeroes of the polynomial represented by the graph is (d) -5.

• The sum of zeroes will be -4-2+1 = -5.

(iii) Find the value of the polynomial represented by the graph when x= 0 (b) -8.

• When the value of x= 0, then y = -8.

(iv) The polynomial representing the graph in the painting by Shruti is (b) cubic polynomial.

• Since there are three zeroes so it is a cubic polynomial.

(v) The sum of the product of zeroes, taken two at a time, of the polynomial represented by the graph is (d) 2

• The sum of the product of zeroes taken two at a time = 2.
