4. f^−1(2)=

5. f^6−1(4)=

Solution

To find the values for f1(x)f^{-1}(x) using the graph of the function f(x)f(x), we need to understand that the inverse function f1(x)f^{-1}(x) essentially swaps the roles of xx and yy. In other words, if f(a)=bf(a) = b, then f1(b)=af^{-1}(b) = a.

Let's analyze the graph to answer each of the questions:

  1. f1(4)f^{-1}(-4): We need to find the value of xx such that f(x)=4f(x) = -4.

    • From the graph, when y=4y = -4, the corresponding xx-value is approximately x=5x = 5.
    • So, f1(4)=5f^{-1}(-4) = 5.
  2. f1(3)f^{-1}(-3): We need to find the value of xx such that f(x)=3f(x) = -3.

    • From the graph, when y=3y = -3, the corresponding xx-value is approximately x=4x = 4.
    • So, f1(3)=4f^{-1}(-3) = 4.
  3. f1(0)f^{-1}(0): We need to find the value of xx such that f(x)=0f(x) = 0.

    • From the graph, when y=0y = 0, the corresponding xx-value is approximately x=1x = 1.
    • So, f1(0)=1f^{-1}(0) = 1.
  4. f1(2)f^{-1}(2): We need to find the value of xx such that f(x)=2f(x) = 2.

    • From the graph, when y=2y = 2, the corresponding xx-value is approximately x=1x = -1.
    • So, f1(2)=1f^{-1}(2) = -1.
  5. f1(4)f^{-1}(4): We need to find the value of xx such that f(x)=4f(x) = 4.

    • From the graph, when y=4y = 4, the corresponding xx-value is approximately x=3x = -3.
    • So, f1(4)=3f^{-1}(4) = -3.

To summarize:

  1. f1(4)=5f^{-1}(-4) = 5
  2. f1(3)=4f^{-1}(-3) = 4
  3. f1(0)=1f^{-1}(0) = 1
  4. f1(2)=1f^{-1}(2) = -1
  5. f1(4)=3f^{-1}(4) = -3
