Answer:
B
Step-by-step explanation:
x² + 9x
to complete the square
add ( half the coefficient of the x- term )² to x² + 9x
= x² + 2( )x + (
)²
= x² + 9x + ← the value of c
= (x + )² ← a perfect square

The range of a function is the set of all values that it can take when its independent variable takes values on the domain.
On the other hand, the range of a function is the domain of its inverse function, if that inverse exists, and vice-versa: the domain of a function is the range of its inverse function, if that inverse exists.
In the case of the given equation:
The inverse function exists since the function is linear, and it can be found by isolating <em>x</em>:
If the range of the original function is the set given by the number {
The power rule (or law of indices) related to root is given
