What is the value of f(−1) when f(x)=2x+2 ?

f(−1)=  0

(I did the test)

Hope I Helped.

is should be y = 5x

step-by-step explanation:

correct me if im wrong

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:
