If the function f is defined by f(x)={{:...

If the function `f` is defined by `f(x)={{:(3x-2",",x gt 3),(x^2-2",",-2 le x le 2),(2x-1",",x lt-3):}` then find the values, if exist, of (iv) `f(-4)`

Text Solution

Verified by Experts

The correct Answer is:
`Lt_(x to1^(-))f(x)=1, Lt_(x to1^(+))f(x)=1`, limits exists
