Given:
The graph of an invertible function 
<em> </em>is given.
To find:
The value of 
.
Solution:
We know that, if the graph of an invertible function passes through the point (a,b), then the inverse function 
passes through the point (b,a).
From the given graph it is clear that the graph of the function passes through the points 
.
So, the inverse function must be passes through the point 
.
Therefore, the value of inverse function is 
at 
. So, the value of is .
Answer:
The roots of the equation are
<h3>- 4 and 4</h3>
Step-by-step explanation:
First rewrite the expression
That's
x² - 16
16 = 4²
So we have
x² - 4² = 0
Using the identity
<h3>a² - b² = (a + b)(a - b)</h3>
Rewrite the expression
So we have
x² - 4² = 0 is
( x + 4)( x - 4) = 0
x + 4 = 0 x - 4 = 0
x = - 4 x = 4
The roots of the equation are
- 4 and 4

Answer:
a) 98 degrees.
b) 8 degrees.
Step-by-step explanation:
supplementary angles: 2 angles that add up to 180 degrees.
a) to find the supplementary angle, all we have to do is:
180 - 82 = 98 degrees
Complementary angles: 2 angles that add up to 90 degrees.
b) to find the complementary angle, all we have to do is:
90 - 82 = 8 degrees
