How do i find the domain & range of
y=2x-4 ?

graph is linear:

y=2x-4

solve for x=o

y=2x0-4       Eliminate 0

y=-4             solved for y

solve for y=0

0=2x-4          add 4

+4      +4

4=2x             divide by 2

/2    /2

4/2 =x

2=x               solved for x

calculate the slope

Solve for x=1

y=2x1-4

y=2-4

y=2             solved for y

Calculating the slope

       y                -y

a= x=1      x=0     =2

             1

The graph is

(0, -4)  (2, 0)

the answer is c)8
