# Find The Inverse Function Values from Tables

Questions With Detailed Solutions

How to find the values of the inverse of a functions given by tables? Grade 11 math questions are presented along with Detailed Solutions and explanations are included.

f , c) ^{ -1}(6) f , d) ^{ -1}(9) f , e) ^{ -1}(10) f
^{ -1}(-10) .
a = f if and only if ^{ -1}(- 4)- 4 = f(a) ,
Which means that a is the value of x such f(x) = - 4.
Using the table below for x = 6, f(x) = - 4. Hence a = 6 and therefore f^{ -1}(- 4) = 6 b) a = f if and only if ^{ -1}(6) f(a) = 6There is no value of x for which f(x) = 6 and therefore f is undefined.
^{ -1}(6) c) a = f if and only if ^{ -1}(9) f(a) = 9The value of x for which f(x) = 9 is equal to - 4 and therefore f^{ -1}(9) = - 4 d) a = f if and only if ^{ -1}(10) f(a) = 10There is no value of x for which f(x) = 10 and therefore f^{ -1}(10) is undefined.
e) a = f if and only if ^{ -1}(-10) f(a) = - 10
The value of x for which f(x) = -10 is equal to 8 and therefore f
^{ -1}(-10) = 8
Use the table below to find the following if possible:
g , c) ^{ -1}(-10) g , d) ^{ -1}(- 5) g , e) ^{ -1}(-7) g
^{ -1}(3) . (Solutions and explanations are included) |
