Shouldn't the domain of f(x+1) be -18 ≤ x ≤ (π/3) - 1??

thanks for your reply, That doesn't make sense to me. My incorrect thinking goes like this.. What is f(x+1) actually saying? To me its saying: apply the function f (which is to square) to the domain x (defined above) +1..making the domain of f(x+1) -16 to π/3 + 1

Hey, I'm just starting out with calculus and am giving the Spivak book a try per threads on here. In the introduction to functions chapter spivak defines a function f(x) =x^2. for all x such that -17 ≤ x ≤ π/3 Then says you should be able to check the following assertion about the function...

How I am currently imagining it: In a simple circuit with just a battery and resistor the voltage of the battery sets the electrons off through the circuit at some speed and that speed is proportional to the voltage. The electrons then encounter the resistor. From these forums my...
