Find the zeros of the function.
Write the smaller solution first, and the larger solution second.
f(x) = 5x^2 – 20
smaller x =
larger x =

true

step-by-step explanation:

i would say b) is your answer

sorry if im wrong

step-by-step explanation:

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:
