If f(x-1) = x^2, find f(3). It’s suppossed to be 16, but I don’t understand why.

Put x=4 and then this equation will give you
f(3)=4²=16

Hi,

this is very straightforward.

Put x = 4 in the given eqaution,

f(4-1) = 4², f(3) = 16

thanks.......................................................................................................

In the domai part its is given the value x-1 = 3 …..

so, choose, x = 4 and put in the function and get the value..
You ust assure for the value you are defining, it should be in valid domain....
Good Luck.......................................................................................................
