Hey there :)
f (x) = 5x² - 2x
g (x) = 3x² + x - 4
( f + g )( x ) is f ( x ) + g ( x )
5x² - 2x + 3x² + x - 4
Combine like-terms
5x² + 3x² - 2x + x - 4
8x² - x - 4
Your option will be the third option
The answer is -x^2 -4 because f(x) is x^2 so -x^2 would be the opposite going downwards. And the graph is on the -4 spot so it’s -4
Answer:
2n - 2
Step-by-step explanation:
n can represent the number, and subtract by 2 since it says decreased by
Here is a picture of the graphed function.
The grey dots are, from left to right:
(-3,0)
(-1,-4)
(0,-3)
(1,0)
According to the valence number of copper(2+) and the same value for chlorine (1-) copper (II) chloride has the formula of CuCl2
The molar mass of copper is 0,0635 kg/mole and chlorine gas a molar mass of 0,035 kg/mole the compound will have a molar mass of ( 0,0635+2×0,035 )kg/mole=0,099kg/mole and 0,344 moles are equivalent in mass to 0,344×0,135 kg=0,046 kg
