Melissa is planning to invest a total of $12,000 in two accounts. if she invests $8,000 in a savings account paying 6% annual simple interest, at what rate does the remainder of her money need to be invested so that the two investments together yield at least $950 in yearly simple interest? (set up and solve an inequality to answer this question.)

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
