Si alguien dice “estoy mintiendo”, ¿está diciendo la verdad?

if x decreases by 4 then y increases by 10

step-by-step explanation:

144.50

step-by-step explanation:

21.5 x 13.4=288.10 divide by 2

there still no table

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
