we know that
The exponential function is of the form
where
a is any value greater than
In General:
It is always greater than , and never crosses the x-axis
It always intersects the y-axis at
Its Domain is the Real Numbers
Its Range is the Positive Real Numbers
Examples
Let
1) For
2) For
3) For
4) For
therefore
the answer is the option
D.) exponential
Answer:
The probability that it will still be working after one week is
Step-by-step explanation:
Given :
Total number of bulbs = 25
Number of bulbs which are good condition and will function for at least 30 days = 5
Number of bulbs which are partially defective and will fail in their second day of use = 10
Number of bulbs which are totally defective and will not light up = 10
To find : What is the probability that it will still be working after one week?
Solution :
First condition is a randomly chosen bulb initially lights,
i.e. Either it is in good condition and partially defective.
Second condition is it will still be working after one week,
i.e. Bulbs which are good condition and will function for at least 30 days
So, favorable outcome is 5
The probability that it will still be working after one week is given by,
