Ineed with this . it’s about order of operations (don’t do the ones i already did). i need finding a problem that equals 2,3,4,7,8, and 11. example: 3-2+(4x5)

a box 3 3/4 feet long or 4+ feet.

step-by-step explanation:

just sum

10 + 10 = 20

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
