I'm using the ti84 plus and yur 3rd one is perfect for me. IRR(-135000,{50000,40000,30000,50000}) = 10.07063 what does the {1,1,1,1} represent in this problem? Thanks peter. I’m using the ti84 plus and yur 3rd one is perfect for me.
IRR(-135000,{50000,40000,30000,50000}) = 10.07063

what does the {1,1,1,1} represent in this problem?

It will be set up to display nonreal answers now. For nonreal answers, just use:

Prompt A,B,C
:( (-B+ROOT(BSQUARED-(4*A*C)))/(2*A)->Q
:( (-B-ROOT(BSQUARED-(4*A*C)))/(2*A)->Z
:D isp Q
:D isp Z
-> is the STO button
* is times
ROOT is the square root button
SQUARED is X2 or the square button

But go into mode, go down 6 times, then go right once, and just push enter. It will be set up to display nonreal answers now.

IRR(-135000,{50000,40000,30000,50000}, {1,1,1,1}) =10.07063
is the same as:
IRR(-135000,{50000,40000,30000}, {2,1,1,1}) =10.07063
and the same as:
IRR(-135000,{50000,40000,30000,50000}) =10.07063
