A) y - 1 = -2(x - 5) b) y - 2 = 5(x - 1)

c) y - 1 = 5(x - 2)

d) y - 5 = -2(x - 1) plz help

x = 3 ± √(5+y)

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
