F(2) if f(x) = 2x - 5

The answer is 4.

Step-by-step explanation:

f(2) = -1

Step-by-step explanation:

Plug in 2 for x in the equation: f(2) = 2(2) - 5

Remember order of operations/ PEMDAS

f(2) = 4-5                  

f(2) = -1

7/2

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:
