The cost of producing transistors decreases by 20% every year. If it currently costs $550 to produce a billion transistors, how much will it cost to produce a billion transistors in 6 years?
If necessary, round your answer to the nearest cent.

ƒ = 0.03b

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
