the function f(x) is invertible. find f^(-1)(-5). f^(-1)(-5) =
Answer
Answer:
- 4
Explanation:
Step1: Recall inverse - function property
If (y = f(x)) and (f) is invertible, then (f^{-1}(y)=x) when (f(x) = y).
Step2: Locate (y=-5) on the graph
We need to find the (x) - value for which (f(x)=-5). Looking at the graph of (y = f(x)), when (y=-5), the corresponding (x) - value is (x = - 4). So (f^{-1}(-5)=-4).
