shifting functions horizontally

OpenStudy (dannyrod2000):

OpenStudy (anonymous):

(x+3)^2

OpenStudy (anonymous):

do you understand the shifting idea?

OpenStudy (dannyrod2000):

thanks

OpenStudy (dannyrod2000):

yup kinda

OpenStudy (anonymous):

danny, you are starting from the origin which is 0,0 and shifting either to the left or right... if you are going left, it is (+) and if you are going right, it is (-)

OpenStudy (dannyrod2000):

i know when to put negative a positive

OpenStudy (anonymous):

hopefully that helps you :)

OpenStudy (dannyrod2000):

thanks

OpenStudy (dannyrod2000):

i going to put more of these. do you mind to wait please? @mathstudent55

OpenStudy (anonymous):

do you want me to help you or @mathstudent55?

OpenStudy (mathstudent55):

When you replace x with x - h, the function shifts h units horizontally. It shifts h units right if h is positive and h units left if h is negative. Here the original function is f(x) = x^2 A shift of 3 units to the left means h = -3 That means replace x with x - h, x - (-3) = x + 3. The new function is g(x) = (x + 3)^2

OpenStudy (mathstudent55):

ok

OpenStudy (dannyrod2000):

both

OpenStudy (dannyrod2000):

OpenStudy (anonymous):

OK, so we shifted 2 units to the right

OpenStudy (mathstudent55):

What shift do you have (how many units and right or left)?

OpenStudy (anonymous):

how do you represent that algebraically?

OpenStudy (dannyrod2000):

wait sry i put wrong one

OpenStudy (dannyrod2000):

OpenStudy (anonymous):

that is the same one

OpenStudy (dannyrod2000):

can you wait i keep putting wrong one

OpenStudy (dannyrod2000):

OpenStudy (dannyrod2000):

ok there @jtryon

OpenStudy (anonymous):

ok, identify what kind of shift it is, and how far it is shifting in units?

OpenStudy (dannyrod2000):

it is going right which is negative and also down and it is also negative so do i add the both negatives?

OpenStudy (dannyrod2000):

-4 and -4 is -8

OpenStudy (dannyrod2000):

so (x-8)^2?

OpenStudy (anonymous):

you are only dealing with horizontal shifts, so it is not going down and it is actually shifted to the left

OpenStudy (anonymous):

when you shift to the left, that is positive so it would be (x+3)^2

OpenStudy (anonymous):

do you see that?

OpenStudy (dannyrod2000):

no

OpenStudy (anonymous):

it is not shifting up or down because you are still on 0 for the y-axis

OpenStudy (dannyrod2000):

nope it is wrong

OpenStudy (dannyrod2000):

it is (x-2)^2-4

OpenStudy (anonymous):

that is not what you had on the graph

OpenStudy (mathstudent55):

The latest graph you showed is the very first one again. It is a parabola shifted 3 units left.

OpenStudy (anonymous):

Thanks @mathstudent55

OpenStudy (dannyrod2000):

i attached another one @mathstudent55 @jtryon
