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

2nd function is even function.

Step-by-step explanation:

Given Functions are

Even Functions are functions whose value didnt change if we replace the variable with negative of the variable.i.e., f(x) = f(-x)

here,

1st function

replacing x by -x we get

∴ It is not an even function.

2nd function

replacing x by -x we get,

∴It is an even function.

3rd function

replacing x by -x we get,

∴It is not an even function

4th function

replacing x by -x we get,

∴It is not an even function

Therefore, only 2nd function is even function.

the answer is 0.3175 hope that you ^w^

also you might actually want to put this picture up if you want people to solve it luckily i remember this question

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.
