If f(x) is an even function, which statement about the graph of f(x) must be true?
-it has rotational symmetry about the origin.
-it has line symmetry about the line y = x.
-it has line symmetry about the y-axis.
-it has line symmetry about the x-axis.

the answer will be the last one

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.

can i see the following ?
