If a girl has 4 seeds, 3 blue ones, and 1 purple one. What is the probability of her choosing a purple one?

¼

Step-by-step explanation:

From the question given above, the following data were obtained:

Blue (B) seed = 3

Purple (P) seed = 1

Total (S) = 1 + 3 = 4

The probability of her choosing a purple seed can be obtained as follow:

Event of purple seed, n(P) = 1

Total, n(S) = 4

Probability of purple seed, P(P) =?

P(P) = n(P) / n(S)

P(P) = ¼

Therefore, the probability of her choosing a purple seed is ¼.

Step-by-step explanation:

The given equation is

For this function to have an inverse, we must restrict the domain, say

We interchange x and y to get,

We now make y the subject to get;

We divide through by 16 to get;

We now take the square root of both sides to get;

Since  , the inverse function is
