Answer:
(0,∞)
Step-by-step explanation:
Given:
It is an exponential function whose base is 9.
If base is greater than 1 then function is growth exponential.
Domain: All real value of x.
Range: It is output value of function we get by putting x.
For x approaches to infinity , y → ∞
For x approaches to negative infinity, y → 0
Range: All positive real number.
Range: (0,∞)
Hence, The range of the given function is (0,∞)
Given:
The given point is (-4,1)
Let's check the ordered pair (-4,1) in the first equation
Hence, (-4,1) is a solution of the first equation x-5y=-9.
Now, let's check (-4,1) in the second equation.
So, (-4,1) is a solution of the second equation 4x+4y=-12.
Hence, (-4,1) is a solution of both equation in the system, then it is a solution to the overall system.

The vector AB is not related with the vector CD as k is not the same for each pair of components.
<h3>Are two vectors similar?</h3>In this question we must prove if the vector AB is a multiple of the vector CD, that is:
(1, 4) - (2, 3) = k · [(- 2, 2) - (1, 3)]
(- 1, 1) = k · (- 3, - 1)
Hence, the vector AB is not related with the vector CD as k is not the same for each pair of components.
