Explanation:
Note how the curve goes through (0,0). So this means that plugging in x = 0 should lead to y = 0. Let's see which choices do that for us
choice A) y = 2^x - 1 = 2^0 - 1 = 1-1 = 0
choice B) y = 2^(x - 1) = 2^(0 - 1) = 2^(-1) = 0.5
choice C) y = 2^x + 1 = 2^0 + 1 = 1+1 = 2
choice D) y = 2^(x + 1) = 2^(0 + 1) = 2^1 = 2
Only choice A has x = 0 lead to y = 0, which is why choice A is the answer

For every 9 pieces in Ren's handful of trail mix, there are 2 raisins.
Step-by-step explanation:
Since we have given that
Number of peanuts = 6
Number of raisins = 4
Number of cranberries = 3
Number of chocolates chips = 5
Total = 6+4+3+5=18
If for every 9 pieces in Ren's handful of trail mix, there are 2 say'x'.
According to question,
And we know that there are 4 raisins.
Hence, for every 9 pieces in Ren's handful of trail mix, there are 2 raisins.
