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-coordinate of these points also the zero of the polynomials?
​

Answer 1

Answer:

ans is below

Step-by-step explanation:

i)

y=2x+5

if x=0,y=5

if x=2,y=9

if y=5,x=0

if y=0,x=2.5

ii)

y=2x−5

if x=0,y=−5

if x=2,y=−1

if x=3,y=1

iii)

y=2x

if x=0,y=0

if x=1,y=2

if x=2,y=4

if x=3,y=6
