Given:
Consider the given function is .
To find:
The remaining zero and y-coordinate of y-intercept.
Solution:
We have,
For zeros, .
So, three zeros of given function are -1, 3 and -2.
Putting x=0 in the given function, we get
So, the y-coordinate of y-intercept of the given function is 6. It means the y-intercept is at point (0,6).
Therefore, the zeros of the function are –1, 3, and -2 and the y-intercept of the function is located at (0,6).

The exponential distribution is:
where
The probability we want is how likely will a dvd player last more than 8 years, given it has already lasted 5 years
To find this, you use conditional probability.
where A is P(x>8) and B is P(x>5)
To find these probabilities, integrate over the distribution:
Sub into conditional probability formula:
Final Answer: Given a dvd player is more than 5 years old, the probability that it will last another 3 more years is about 54.9%
