Question

Y = 3x +1; domain = {-1, 0, 1} HELP PLEASE

Answer 1

Answer:

-1,0

Step-by-step explanation:

Answer 2

We have to put values of domain to find range

$\\ \ast\sf\longmapsto y=3x+1$

$\\ \ast\sf\longmapsto D_R=[-1,0,1]$

$\\ \ast\sf\longmapsto y=3(-1)+1=-3+1=-2$

$\\ \ast\sf\longmapsto y=3(0)+1=0+1=1$

$\\ \ast\sf\longmapsto y=3(4)+1=12+1=13$

Now

$\\ \ast\sf\longmapsto R_R=[-2,1,13]$
