Hello guys, I'm still learning how to do more advanced techniques with the TI-Nspire. Can you help me figure this one problem that I'm having out?
I'm using the right difference quotient. f(x+h)-f(x)/h
For (fx) = x^2-4x+7, find f(x+h)-f(x)/h
msec =
TI Nspire Function
rightdiff(x,h):= f(x+h)-f(x)/h
when I plugin rightdiff(x^2-4x+7, h) The answer is not coming out reduced as 2x+h-4.

Re: Using the Difference Quotient on the TI Nspire
You meant
If you type
Don't type
$mathjax$\dfrac {f \left({x + h}\right) - f \left({x}\right)} h$mathjax$
, so you probably forgot parentheses around f(x+h)-f(x)
, which made only f(x) to be divided by h.If you type
rightdiff(x,h)
in, you indeed get 2*x+h-4
Don't type
rightdiff(f(x),h)
though, as the f(x) is already in the function definition (maybe that was your mistake)-
