Determine whether each function is even, odd, or neither. f(x) = x²_9

g(x) = |x-3

f(x) = 22-1

g(x) = x + x2

The decibel level of sound is 50 db greater on a busy street than in a quiet room where the intensity of sound is watt/m2. the level of sound in the quiet room is db, and the intensity of sound in the busy street is watt/m2. use the formula , where is the sound level in decibels, i is the intensity of sound, and is the smallest sound intensity that can be heard by the human ear (roughly equal to watts/m2).

Which function is odd check all that apply a. y=sin x b. y=csc x c. y=cot x d. y=sec x
