Graph f(x)= -2x + 4
We can graph this equation by Making Table
Assume values of x and substitute it to find y.
x y
-1 6
0 4
2 0
f(x)= -2x + 4, if x = -1
= -2(-1) + 4
= 2 + 4
= 6
f(x)= -2x + 4, if x = 0
= -2(0) + 4
= 0 + 4
= 4
f(x)= -2x + 4, if x =2
= -2(2) + 4
= -4 + 4
= 0
Plot the points (-1,6), (0,4), (2,0)
