So domain is the number you can use
range is the output your get from inputting the domain given
so from 2≤x≤5
since it is linear, we can be sure that we only need to test the endpoints of the domain to find the endpoints of the range
sub 2 for x
y=2(2)+1
y=4+1
y=5
sub 5 for x
y=2(5)+1
y=10+1
y=11
so range is from 5 to 11
in interval notation: [5,11]
in other notation 5≤y≤11
or
R={y|5≤y≤11}
The answer can be 6/1 or just 6. And visit www.caculatorsoup.com
Choice b would be correct since the slope of the line is negative !
Answer:
6 and 7
Step-by-step explanation:
lol just use a calculator ツ
