Select the correct answer. triangle abc underwent a sequence of transformations to give triangle a′b′c′. which transformations could not have taken place? a. a reflection across the line y = x followed by a reflection across the line y = -x b. a reflection across the x-axis followed by a reflection across the y-axis c. a rotation 180° clockwise about the origin followed by a reflection across the line y = x d. a reflection across the y-axis followed by a reflection across the x-axis

any options?

step-by-step explanation:

3 3 6, because in every triangle the longer side is always shorter than the sum of the other two

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
