Answer:
No it is not a function because the 10 in the input is repeated twice (the arrow is connected to 2 numbers)
D= {7, 9, 10}
R= {7, 9, 8, 10}
The pairs are (7, 7), (9, 9), (10, 8), (10, 10)
The answer should be A. In order to solve these half-life problems, I encourage you to find an algebra calculator online, and plug in these numbers. The remaining grams goes in front, so 3.
The entire equation should look something like 3 = 15(1/2)^t/4.95
The 4.95 represents how long it takes before the sample halves, t is your answer, 1/2 represents the value halving every 4.95 hours, 15 is the initial sample size, and 3 is the end result that remains.
The overall answer should be about 11.5 hours, as per an algebra calculator.
Hope this helps solve any other similar problems
Your answer would be 1+1=2
This took me a while to figure out

Answer:
y = 260
Step-by-step explanation:
locate x = 7 on the x- axis, go vertically up to meet the graph at (7, 260 )
when input is 7 then output y = 260
