The graph of a function f(x) is shown below: plot ordered pairs negative 1, negative 3 and 0, 1 and 1, 2.2 and 2, 3 what is the domain of f(x)?

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:

x = 12

y = 1

for the points!
