Which step is included in the construction of perpendicular lines using a point on the line? Make arcs above and below the given line with a compass. Create two arcs above the given line with a straightedge. Connect two created arcs together with a compass. Measure the constructed angles with a straightedge.

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
