The high temp today was 62 degrees when night time comes, the temp will drop 40 degrees. by 4 am the temp will drop an additional 40 degrees. what is the temp at 4a,

The temperature at day today = 62 degrees

Since at night the temperature will fall by 40 degrees, the temperature at night = 62 - 40 = 22 degrees

By 4 AM, the temperature will again fall by 40 degrees, so the final temperature at 4 Am = 22 - 40 = - 18 degrees

We can now conclude that there are two successive falls of 40 degrees.

Therefore, the temperature at 4 AM will be -18 degrees (negative)

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!
