A 4m flagpole is not standing up straight. There is a wire attached to the top of the pole anchored in the ground. The wire is 4.17m
long. The wire makes a 68° angle with the ground. What angle
does the flagpole make with the wire?

answer: the answer is e

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
