Question

Draw the graph of (i) y = 2x + 5, (ii) y = 2x – 5, (iii) y = 2x and find the point of intersection on x-axis. Is the x-coordinates of these points also the zero of the polynomial?

Answer 1

i hope it will help you

Answer 2

Answer:

Refer the attached figure below.          

Step-by-step explanation:

Given : Equations

(i) y = 2x + 5, (ii) y = 2x – 5, (iii) y = 2x

To find : The point of intersection on x-axis. Is the x-coordinates of these points also the zero of the polynomial?

Solution :

We plot the equations with the help of graphing tool.

Equation (i) $y=2x+5$ plotted with red line passing through point (-2.5,0).

Equation (ii) $y=2x-5$ plotted with blue line passing through point (2.5,0).

Equation (iii) $y=2x$ plotted with green line passing though point (0,0).

Yes, The x-coordinates of these points also the zero of the polynomial.
