I have a Piecewise function, that looks like,
-x , for x < - 1
4- X^2 , for -1 < X < 2
SQRT X-2 -1 , 2 < X < 11
Solve f (x) = 0
I am having troubles find where to start.
Do I want to plug in and solve = 0 to each equation?
To get you started:
Does f(x) = 0 have a solution on the interval x<-1? (That's the interval .)
Solve f(x)=0 on the interval x<-1.
So solve -x=0 on the interval x<-1.
That equation has one solution, x=0, but x=0 isn't in that interval (x<-1, the interval ).
Therefore f(x) = 0 has no solutions on the interval x<-1 ( the interval ).
