Question

The graph of a quadratic polynomial is shown in the given figure. The sum of the zeroes of the polynomial is:

Options

• –2

• –1

• –3

• 3

Answer 1

–2

Explanation:

Finding zeroes from the graph:

The zeroes of a polynomial are the x-coordinates of the points where the graph intersects the x-axis.

From the given graph, the parabola cuts the x-axis at:

x = –4

x = 2

Sum of zeroes:

Sum = –4 + 2

Sum = –2
