translate a piecewise function

[Travis Bower]

Hi,

I can move a simple function from its endpoints and from its center.

I wanted to do the same with a piecewise function, but I cannot.  True?

I tried to make a locator point on the p. function and drag that, but it did not work.  [the point moves, but not the function]

My workaround is to create sliders and that works.  

I was hoping to manipulate the function, not the parameters/sliders.

Any thoughts?

Key is ‘simple function’

 

Only ‘certain’ functions are interactive. (linear, quadratics (in the right form!), basic trig.)

Sliders for the rest.

 

Be Excellent,

Ah, but sliders aren’t the only way to control parameters.

You can make a point control the parameters. In the image below, the point has variables (h,k).

I’ve put a –3 at the end of f2(x) so that the point is on the piecewise function. I can now move the function by dragging the point.

To think: it’s been 17 YEARS since the birth of TI-NSpire!!!

My bad: 13 YEARS.

2020-2007=13, not 17.

@17 I was starting to feel old, so thanks for the correction.  I am now rejuvenated.

Linking to (h,k) was what I wanted to do.  Thanks Marc.
