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

Best ResponseYou've already chosen the best response.0I am saying that f(x) is an even function, if it satisfies f(a)=f(a) for any value of a. for example, you have to have f(1)=f(1)

Best ResponseYou've already chosen the best response.0in your options, there is only one such function that satisfies f(a)=f(a) which on do you think it is and why?

Best ResponseYou've already chosen the best response.0So it's A. g(x) = (x – 1)2 + 1 ?

Best ResponseYou've already chosen the best response.0plug in a and a into each option and set them equivalent to each other: (like this ) \((a1)^2+1=(a1)^2+1\) \(2(a)^2+1=2(a)^2+1\) \(4(a)+2=4(a)+2\) \(2(a)=2(a)\)
