If the probability of getting heads is 1/2 and you flipped a coin 200 times you would land on heads 100 times
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}
Answer:
B: Y=1/2×+2 I think that's it
Answer:
y=5x+6
Step-by-step explanation:
+6 is six more than.
5x is five times the input.
For example, let's say x=3. you gotta multiply first so you can get the five times out of the way. 3×5=15. Now we got to add six because "6 more than" means to add six. so, 15+6=21. I plugged in 21 for y to check and I got x=3, so this works.
