To find the right exponential function, we can just take x-values an replace them into the given functions. The one that give the correct y-values will be the answer.
For , let's see which function gives
You can observe that function A is not the correct one, because it gives a positive result. However, function B can actually be the answer, because it woud give the same y-value than A but negative, as we need. Let's see

We are given with the total number of students which is 160 on which 40 students are honors and 60 are athletes' Solving for the probability that the chosen student is an athlete given that he is also an honor is P = 40 / 160. P= 1/4 Solving for the probability that the chosen student is an honor student given that he is also an athlete is P = 60 / 160 P = 3/8
Then solving for the unknown, we have: P=(1/4) x(3/8) P=3/32
=> to multiply fractions we multiply the numerators ( top numbers ) with each other and the denominators (bottom numbers ) also the same way ... => 2/7 x 1/3 = 2/21 => 6/11 x 22/30 = 132/330 = 2/5 => 1/8 of 32 = 1/8 x 32/1 = 32/8 = 4 => 2 1/2 x 5 1/3 => first convert 2 1/2 and 5 1/3(which are mixed fractions) into an improper fractions ...=> 5/2 x 16/3 => 80 /6 = 40/3
=> for dividing fractions we take the reciprocal of one fraction and then multiply ...
