Answer: D.The domain and range of the function are the same.
Step-by-step explanation: Given function f(x)=-√-x.
The given function is a square root function and we have minus sign in front of x inside square root.
A square root always defined for positive values or 0.
In order to get a positive number or 0 inside square root, let us solve the inequality:

On dividing both sides by -1, the inequality sign would get flip and we get
<h3>Domain:

</h3>
We can see that we have a negative sign in front of square root. So, the value of f(x) would be always a negative number or 0.
<h3>Therefore, range would also be :

.</h3><h3>Therefore, correct option is D option.</h3>
Answer:
7x + 14
Step-by-step explanation:
Answer:
The turning point of a parabola is the vertex
Vertex form of a quadratic equation: 
(where (h, k) is the vertex and a is the coefficient of the variable x²)
Given:

- vertex = (-1, 3)
Therefore, a = 1
Substituting a = 1 and the given vertex into the equation:




Therefore, a = 2 and b = 4
