Answer:
The domain is found depending on the information you're given. In a table, the domain is found by taking all the x values given and listing them least to greatest. Same with ordered pairs. In a graph, the domain is found by first seeing if there are any restrictions and then find the x values that work and have one output.
The range is found the same way, but with the y values.
Hope this helps!!

<h2>
y = 2x + 6</h2>
Step-by-step explanation:

y = 2x + b passes through point (-3, 0), so:
0 = 2(-3) + b
0 = -6 + b
b = 6
Therefore the equation: <u>y = 2x + 6</u>
Answer:
a. 16
b. 80
c. Blood type AB
Step-by-step explanation:
Given:
O = 45%
A = 40%
B = 11%
AB = 4%
Total number of donors = 145
a. No. of donors that had type B blood = 
Type B blood donors ≈ 16
b. No. of blood donors without blood type O = 
Those without blood type O ≈ 80
c. Find the number of people that had type AB:
Type AB =
≈ 6. This is less than 10 donors.
Therefore, blood type AB had less than 10 donors.
