What are the solutions of the quadratic equation (x  + 3)2  = 49? a)  x  =  –2 and  x  =  –16b)  x  =  2 and  x  =  c) x  = 4 and  x  = –10d)  x  = 40  and  x  =  –58

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
