Best first answer will get ! 25 ! harold wants to get at least a grade of 90 in math class. his grade will be the average of two test scores. he got a 86 on the first test. what is the lowest grade harold needs to get on his second test to meet his goal?

think the answer is 30 degrees. if not than it is 20 degrees. not 100% sure. let me know if it was right.

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
