x = [-8±√(8²-4·1·15)]/[2·1] = [-8±√4]/2 = -3, -5

make factors from the roots

x²+8x+5 = (x+3)(x+5)

Given the table of values below, which of the following ordered pairs are found on the graph of the inverse function? A. (-2, -1
Ainat [17]

Given:

The of values of a function.

To find:

The ordered pairs that are found on the graph of the inverse function.

Solution:

If a function is defined as

f(x)=\{(x,y):x\in R,y\in R\}

Then its inverse function is defined as

f^{-1}(x)=\{(y,x):x\in R,y\in R\}

From the given table it is clear that, the ordered pairs of the function f(x) are :

\{(-2,-14),(-1,10),(0,6),(1,2),(2,-2)\}

So, ordered pairs of the inverse function are :

\{(-14,-2),(10,-1),(6,0),(2,1),(-2,2)\}

Therefore, the correct option is B.
