Ayoung sumo wrestler decided to go on a special diet to gain weight rapidly. he gained weight at a constant rate.

the table compares the wrestler's weight (in kilograms) and the time since he started his diet (in months).

how fast did the wrestler gain weight?

kilograms per month

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function

you can not solvr this without numbers
