Find the range of F(x)= (x+1)^2-1

Question

Find the range of the function

Answer 1

y=(x+1)^2 -1...parabola with vertikal axis . . . tu get lo spot, dy/dx=2x+2=0 at x=-1 . . . giv y=-1 at x=-1....point=(-1,-1) . . . raenj av y=from -1 tu infinity

Answer 2

"Solution: Given F(x)= (x+1)^2-1
find the range of the function
let f:R->R
there for the range of the function =F>=-1"
