The altitude at which we boil an egg affects how long it takes for the egg to achieve perfect hardness.

it takes 198 seconds to boil a perfect egg at the lowest place possible, the edge of the dead sea, which has an

altitude of -418 meters.

the highest place possible is the summit of mount everest which has an altitude of 8848 meters. it takes 209

seconds to boil a perfect egg there.

t(a) models the time (in seconds) it takes to boil a perfect egg at an altitude of a meters.

which number type is more appropriate for the domain of t?

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!

it’s supposed to be -4+45=41
