Draw right angles triangle ABC with B = 90° in your answer book and find the ratios of the following in terms of the sides. 1.1.1 sinc 1.1.2 sin  1.1.3 cosĈ 1.1.4 cosâ 1.1.5 tanĆ 1.1.6 tanâ

what shape is

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
