14. Is 0.8x = 0.5y-2 a direct variation? If it is, find the constant of variation.
yes; k = 0.625
yes; k = 1.6
yes; k = 2.5
no

your answer would be 10x - 1

you already gave the answer

step-by-step explanation:

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

if i knew id you bro,, my bad
