In the Figure below is shown the graph of this function. We have the following function:
The occurs when , so:
Therefore, the is the given by the point:
From the figure we have three :
So, the occur when . Thus, proving this:
Answer:
f(x) = x² - 81 = ( x+ 9)(x - 9) Difference of two squares
g(x) = x+9/x-9
g(x) . f(x) = x + 9/ x - 9 × (x+9)(x - 9)
= ( x + 9)(x +9)
= ( x + 9)²
= x² + 18x + 81
Hope this helps.
Answer:
15'
Step-by-step explanation:
12 squared + 9 squared =225
144 81
then square root 225 to get 15
