F(x) = x2 + 1 g(x) = 5 – x (f + g)(x) =

x^3 - x^2 - 6x

Step-by-step explanation:

First, add f +g

x^2 + 1 + 5 -x (combine like terms)

x^2 - x +6  

Next, multiply the new equation by x

x(x^2 - x + 6)    Use distributive property

= x^3 - x^2 + 6x

answer: 0,6

step-by-step explanation:

this would make it the y intercept.

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:
