10 points 7. The two circles have different radii and the arcs highlighted in blue are
different lengths. Are the angles marked alpha and beta (the two Greek
letters) also different in measure?
L = 8
( = 4
a
Ar=6
R= 12
O no
O yes, alpha is 2 times bigger than beta
yes, alpha is 2 times smaller than beta
yes, but it's impossible to tell how much different they are

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
