Which of the following is an even function? g(x) = (x – 1)2 + 1 g(x) = 2x2 + 1 g(x) = 4x + 2 g(x) = 2x

I assume the 2s after the x - 1 and x in the first two functions are actually exponents.  

g(x) = (x - 1)^2 + 1 = x^2 - 2x + 2. g(-x) = (-x - 1)^2 + 1 = x^2 + 2x + 1 + 1 = x^2 + 2x + 2. NEITHER.  

g(x) = 2x^2 + 1; g(-x) = 2(-x)^2 + 1 = 2x^2 + 1. Since g(-x) = g(x), this is EVEN.  

g(x) = 4x + 2; g(-x) = -4x + 2. NEITHER.  

g(x) = 2x; g(-x) = -2x. Since g(-x) = -g(x), this is ODD

Step-by-step explanation:

g(x) = 2x2 + 1

Step-by-step explanation:

x^2 is an even function

g(x) = (x – 1)^2 + 1   since this is translated to the left and up.  Translation to the left or right make it lose its parity. It is not even

g(x) = 2x^2 + 1 This is only translated up  so it is still even

x is an odd function

g(x) = 4x + 2   This is shifted up  its is still an odd function

g(x) = 2x  This is still an odd function

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
