What does it mean when a question says if an equation is odd, even, or neither

Even functions are functions that can map onto themselves by a reflection across the y axis
an example is f(x)=x²


odd functions are functions that are reflected across the origin (means one side is flipped across y axis not both sides)
an example is f(x)=x³


to test if it is odd or even or neither, do this test

if it is even, you can replace x with -x and get the same equation
basically if f(x) is an even function then f(x)=f(-x)
exampe
f(x)=x²
f(-x)=(-x)²
f(-x)=x²
same thing, this is even

for an odd one, when you replace x with -x, f(x) turns to -f(x)
basically f(-x)=-f(x)
f(x)=x³
f(-x)=(-x)³
f(-x)=-x³


neither is if it is neither of those like this one
f(x)=x²-2x
if we replace x with -x we get f(-x)=x²+2x and that is not the same function nor is it the negative of the original function

Answer:1/16 for each of us

Step-by-step explanation:

Since only 1/4 is left and you and the teachers are splitting it up,you’d get 1/16 each because the half of 1/4 (1/8) was split into 2 (1/16)
