(3×10⁴)+(6×10³)+(9×10²)+(7×10¹)+(8× 10°) is the same as (a)34697 (b)36978 (c)306978 (d)3006978​

41*67/2=1373.5

step-by-step explanation:

i just used a calculator

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
