YOU WANT TO FRAME A COLLAGE OF PICTURES WITH A 9-FT OF WOOD. WHAT DIMENSIONS WILL HELP YOU MAXIMIZE THE AREA? MAKE A DESIGN OR SKETCH PLAN OF FRAME. USING THE DESIGN OR SKETCH PLAN, FORMULATE PROBLEMS THAT INVOLVES NATURE OF ROOTS OF QUADRATIC EQUATIONS AND THEN SOLVE THEM.

answer: 72: 111

step-by-step explanation:

answer: what are the answer choices?

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 b.
