Best ResponseYou've already chosen the best response.0I believe the vertical shift is down 5, but I don't know about the horizontal shift.

Best ResponseYou've already chosen the best response.2when does the argument for sin equal zero?

Best ResponseYou've already chosen the best response.2in other words y = sin(x) is the parent function its 'center' is defined when x=0 to know how for it shifts on the x axis, the argument of x gets adjusted to read: 2x+pi so when does 2x+pi = 0?

Best ResponseYou've already chosen the best response.0wait, sorry. this lesson confused me a lot. am i supposed to get x alone in 2x+pi=0?

Best ResponseYou've already chosen the best response.0so it would be x= pi/2 ?

Best ResponseYou've already chosen the best response.2correct so our normal value at x=0, has now been shifted over to x=pi/2

Best ResponseYou've already chosen the best response.0so the answer would be down 5 and left pi/2?

Best ResponseYou've already chosen the best response.2what would you say is the value of x for all points on the y axis?

anonymous

Best ResponseYou've already chosen the best response.0doesn't the x value vary depending on what the y is?

Best ResponseYou've already chosen the best response.2dw:1433275550605:dw where do we generally put the y axis? for what value of x does it pass thru?

Best ResponseYou've already chosen the best response.2do not confuse a function, for how we measure the function. the function is a curve, for a given value of x, we can measure how far the curve is from the x axis, by comparing it against the y axis. say we have a function that measures the height of a tree at a given day. the tree is the object that we are measuring (it is the function) the height of the tree is NOT the function, it is how we are measuring it. (the y axis)

Best ResponseYou've already chosen the best response.2if we want to know WHERE the function intersects (crosses over or hits) the y axis ... we should be cognizant of where the y axis is to start with. right?

Best ResponseYou've already chosen the best response.0the y axis usually passes through the 0 on the x axis

Best ResponseYou've already chosen the best response.2got caught in a spin cycle ... but yes, it passes thru where x=0

Best ResponseYou've already chosen the best response.2so, lets compare our functions, when x=0

Best ResponseYou've already chosen the best response.0so for the table, x=0 when y=0?

amistre64

Best ResponseYou've already chosen the best response.2more appropriately: y=0, when x=0, but yeah

Best ResponseYou've already chosen the best response.0so the yintercept of the f(x) table is 0?

amistre64

Best ResponseYou've already chosen the best response.2correct: f(0) = 0 g(0) is what?

anonymous

Best ResponseYou've already chosen the best response.0would it be 3? i think the number at the end is the yintercept but i'm not sure

amistre64

Best ResponseYou've already chosen the best response.2its not the number on the end, is the value when x=0 which in this particular case g = 4 sin(4x)  3 g = 4 sin(0)  3 g = 0  3 is 3, but dont go by "last term", its not a good conjecture.

Best ResponseYou've already chosen the best response.2what is the y intercept of: y = 2cos(x) + 1 ??

amistre64

Best ResponseYou've already chosen the best response.2yep, so "the last term" is not a valid approach is it?

anonymous

Best ResponseYou've already chosen the best response.0no, i see now though. so the yintercept of f(x) would be the answer to that one?

amistre64
 one year ago
Best ResponseYou've already chosen the best response.20 is more than 2, yes g(0) < f(0) 2 < 0

amistre64

Best ResponseYou've already chosen the best response.2or 3 depending on what keys we want to hit ...

Best ResponseYou've already chosen the best response.0haha i understood it! thanks a lot for your help. i'm not too great with math but you were really patient so thank you!
