Question

The graph of the polynomial 2x^2-8x+5 cuts the y-axis at __________

(a) (6, 0)

(b) (0, 7)

(c) (0, 5)

(d) (8, 9)

I have been asked this question during an interview.

My question is from Geometrical Meaning of Zeros of Polynomial in section Polynomials of Mathematics – Class 10

Answer 1

Correct answer is (c) (0, 5)

The explanation: The graph of the polynomial 2x^2-8x+5 cuts the y-axis.

Hence, the value of x will be 0.

y(0)=2(0)^2-8(0)+5

y=5

The graph cuts the y-axis at (0,5)
