To reflect a function across the x axis, we want to turn all the x values that were once positive negative and vice versa. That means we want f(-x), which is:
Answer:
16/81
Step-by-step explanation:
As the tile is taken and then replaced this means that the probability of the second event is not impacted by the probability of the first (they are independent)
As there are 9 tiles and 4 of them are even, the probability that the first tile drawn is even is 4/9.
There are still 9 tiles and still 4 of them are even for the second tile being drawn so this probability is then also 4/9.
If we want to find the probability of both events we should multiply together these two independent probabilities.
So:
