so far you have mostly worked with equations. there are special types of equations, called functions, that have exactly one output for every possible input into the equation. an example of
this in the real world is the amount of money you are charged at a store: the input is the item you
are purchasing, and the output is the money you are charged. individual items have one price, so
this is an example of a function. can you think of any other examples of functions? why might this type of equation be useful?

step-by-step explanation:

it's the only multiple of both and the least

positive

step-by-step explanation:

the quadrant is facing upwards

no i do not : ( what is it?

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
