Using complete sentences, explain how to find the yintercept for each function and determine which function has the largest yintercept.
f(x) = 2 tan(3x + π)
g(x) = 3 sin(4x  π)  2
I have absolutely no idea how to solve for this without just graphing the equations, and I am pretty sure that I have to explain how to find the yintercepts without graphing them. I have tried solving for "x = 0", but I didn't get the correct values for the yintercepts (I graphed these equations to check).

Best ResponseYou've already chosen the best response.0you plug in 0 for x to get the yintercepts. f(x) = 2 tan (3x + π) f(0) = 2 tan (π) f(0) = 0 yintercept (0, 0)

Best ResponseYou've already chosen the best response.0Wouldn't it be f(0) = 2 tan( (3*0) + π ) f(0) = 2 tan(0 + π) f(0) = 2 tan(π)

Best ResponseYou've already chosen the best response.0Oh, I see. So then: f(0) = 2 tan(π) f(0) = 2 (0.0548861508) f(0) = 0.1097723016 This isn't exactly 0 :( This is where I keep struggling :/

Best ResponseYou've already chosen the best response.0And on the graph, it doesn't display as "0.10977..". It says (0, 0). :((

Best ResponseYou've already chosen the best response.0Thank you so much, omg. I would have never thought to do that. I don't even know how to, since I was using my phone. I'll use my computer calculator. So tan(π) = 0 radians?

Best ResponseYou've already chosen the best response.0tan (π radians) = 0 radians is just another way to measure the angle. (π radians = 180°)

Best ResponseYou've already chosen the best response.0but yeah, just put tan π in the calc

Best ResponseYou've already chosen the best response.0It still gives me "0.0548861508" D:

Best ResponseYou've already chosen the best response.0So my calculators were reading it as "3.141592..." and not as "pi radians", then. This makes things so much clearer now. I really appreciate all of your time and help.
