Which of the following inequalities would have a solution of -1 , 1 , 3 , 4 ?

O a > 0

O b ≥ −1

O c < 5

O d ≤ 4

O e > −1

O f ≤ 6

yes

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
