0.375 is the probability of getting two tails when flipping four coins. 0.50 is the probability of being off by one (1 or 3 tails), while 0.125 is the probability of being off by two (0 or 4 tails). Hope it helps I think this is the right answer.

Answer:

g(7)=4

Step-by-step explanation:

We look for where x=7. The way you find the answer is first, find the point (0, 7). Draw a line straight up and down, and see where that line intersects the function. Those intersection points are your answer(there will always be only 1 for a function, but if a graph isn't a function, there might be more than 1).

Using this method here, we see that g(7) intersects our line at (7, 4), so g(7)=4.
