The rational function g(x)=x+10/x can be rewritten in the form g(x)=c+r/x, where c and r are constants. Which expression is the result?

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:

cause it equals more
