Demuestra que los puntos (1,1),(5,3),(8,0)(4,−2), son vértices de un paralelogramo. Además, obtenga su ángulo obtuso, perímetro y área. Si me lo pueden explicar les agradecería mucho u. u

true

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

the answer is  

d.

i did this one. so you should get it right.
