Which functions are even? check all of the boxes that apply.
f(x)=x^4- x^2
f(x)=x^2- 3x + 2
f(x)= sq root (x-2)
f(x)= |x|

if you use photomath right away it will give you the answer not like this app that you have to wait for people.

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
