How would I solve this?:
f(x+1)  =4x^2+3x-2

littlebird · Answer

Im guessing....
where ever x is, replace it with (x+1)
Simplify

are you wanting to find f(x)?

jeansweets · Answer

are you asking for 4x squared?

triciaal · Answer

to solve 
find the values of x that makes this = 0 
or given f(x) = 4x^2 + 3x -2 find f(x+1) ?

$$f(x+1)=g(x) \ \text{ if you want \to find } f(x) \text{ given something like } f(x+1)=g(x) \ \text{ then replace } x+1 \text{ with } u \ \text{ so you have } u=x+1 \ \text{ subtract 1 on both sides } \ u-1=x \ \text{ so you ahve } f(x+1)=g(x) \text{ gives } f(u)=g(u-1) \ \text{ and then evaluate } f(u)=g(u-1) \text{ at } x \ \text{ and you have } \ f(x)=g(x-1)$$
g(x) represents the right hand side of you equality by the way
