Given the function h(p)=p2 + 2p evaluate h(3).

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0

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:
