Line segment EF has endpoints E ( 5, -1) and F (-3,8) what are coordinates of the midpoint EF A segment has midpoint at (2,-4) an endpoint at (5,-9) what are coordinates of other midpoint

8

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
