Answer:
Correct choices are 1 and 4
Step-by-step explanation:
As per data given we have:
- Median temperature is 75°F and 88°F
- And the range from the median is 5° for both cities
This gives us lowest temperatures of:
- 75° -5° = 70° and 88° - 5°= 83° respectively
And high temperatures are:
- 75° + 5° = 80° and 88° + 5° = 93°
<u>Answer choices based on above details:</u>
- Choice 1 - correct
- Choice 2 - incorrect. Correct answer is 93°
- Choice 3 - incorrect. Correct answer is 93° - 70° = 23°
- Choice 4 - correct
They are similar and the answer is SSS
The answer to this question is FALSE.
Domain is the set of all the numbers that we can input to the function or that can be used in place of x. The numbers which make the function undefined are excluded from the domain.
In the given exponential function, there is no any value of x which will make the function undefined, so the domain of the function if set of All real numbers. In general, domain of exponential functions is Set of All real numbers.
To check for continuity at the edges of each piece, you need to consider the limit as 
approaches the edges. For example,
has two pieces, 
and 
, both of which are continuous by themselves on the provided intervals. In order for 
to be continuous everywhere, we need to have
By definition of , we have 
, and the limits are
The limits match, so is continuous.
For the others: Each of the individual pieces of 
are continuous functions on their domains, so you just need to check the value of each piece at the edge of each subinterval.
Answer:
Step-by-step explanation:
The amplitude is half of the range.
a=(maximum-minimum)/2, in this case
a=(2-(-4))/2
a=6/2
a=3
