The solutions to the grade 11 questions on How to Find Inverse Function Values from Graphs are presented.

Answer the following questions
g , c) ^{ -1}(0) g , d) ^{ -1}(- 2) g , e) ^{ -1}(4) g
^{ -1}(8) .
6 = g(a)
Meaning that a is the value of x such g(x) = 6.
Using the graph below for x = 2, g(x) = 6. Hence a = 2 and therefore g
^{ -1}(6) = 2 . b) a = g if and only if ^{ -1}(0) g(a) = 0According to the graph shown, g(- 1) = 0 and therefore g.
^{ -1}(0) = - 1c) a = g if and only if ^{ -1}(- 2) g(a) = - 2The value of x for which g(x) = - 2 is equal to - 2 and therefore g^{ -1}(- 2) = - 2 d) a = g if and only if ^{ -1}(4) g(a) = 4The value of x for which g(x) = 4 is 1 and therefore g.
^{ -1}(4) = 1e) a = g if and only if ^{ -1}(8) g(a) = 8According to the graph of g, there is no value of x for which g(x) = 8 and therefore g is undefined.
^{ -1}(8)
h , c) ^{ -1}(0) h , d) ^{ -1}(- 1) h
^{ -1}(2) .
1 = h(a) ,
Meaning that a is the value of x such h(x) = 1.
According to the graph shown, h(0) = 1 and therefore h.
^{ -1}(1) = 0b) a = h if and only if ^{ -1}(0) h(a) = 0
According to the graph shown, h(π/2) = 0 and therefore h.
^{ -1}(0) = π/2c) a = h if and only if ^{ -1}(-1) h(a) = -1
According to the graph shown, h(π) = - 1 and therefore h.
^{ -1}(-1) = πd) a = h if and only if ^{ -1}(2) h(a) = 2
According to the graph shown, there is no value of x for which h(x) = 2 and therefore h is undefined.
