Which function is even? check all that apply.

Hi there!

The answer is A, and C

Step-by-step explanation:

cos(-x)=cos(x)

sec(-x)=sec(x)

A and C.

Step-by-step explanation:

Graphs that have symmetry with respect to the y-axis are called even functions. So, let's check each of the graphs:

1. As we can see in the graph attached, y=cos(x) is symmetrical with respecto to the y-axis.

2. As we can see in the graph attached, y=sin(x) is not symmetrical with respecto to the y-axis.

3. As we can see in the graph attached, y=sec(x) is symmetrical with respecto to the y-axis.

4. As we can see in the graph attached, y=csc(x) is not symmetrical with respecto to the y-axis.

4.

Step-by-step explanation:

We know that

If f(x)=f(-x)

Then, the function is called  even function.

1.

Hence, the function is not even.

2.

Hence, the function is not even.

3.

Hence, the function is not even.

4.

Therefore, the function is even.

Option (4) is true.

A and D

Step-by-step explanation:

solve for each with f(x)= f(-x)

Answer A and B on edg 2020

Step-by-step explanation:

F=X=1X=A2=1

Step-by-step :I am a grown up

F=X=1X=A2=1

Step-by-step explanation:

it prefer it if you give someone thank you

If a function is even, it gives the same result for positive and negative inputs such as 8 and -8.

From the choices, the even functions are D and A.

D because the absolute value thing makes any input positive, and A because any number raised to an even power gives a positive result.

im pretty sure its

(A) y=cos x

(B) y=sec x

None of the functions is even

Step-by-step explanation:

In order to check the function is even or odd, we put -x in the function, if the answer is as it is as the original function then the function is even.

So,

The function is not even.

This function is not even

This function is also not even

This function is also not even..
