Given the function f (2x-3) = 2x-1, find the expression of function f (x)

Given the function f (2x-3) = 2x-1, find the expression of function f (x)


Let t = 2x-3, then x = t / 2 + 3 / 2
F(t)=2(t/2+3/2)-1=t+2
So f (x) = x + 2



Let f (x) = 2x + 3, G (x + 2) = f (x), then the expression of G (x) is [] why?
A.2x+1
B.2x-1
C.2x-3
D.2x+7


Let f (x) = 2x + 3, G (x + 2) = f (x), then the expression of G (x) is []
B
g(x)=f(x-2)=2(x-2)+3=2x-1



Let f (x) = 2x + 3, then the expression of F (x-1)


Substituting X-1 into f (x) = 2x + 3
We get f (x-1) = 2 (x-1) + 3 = 2x + 1
