Answer:
choose x ≥ 0 or x ≤ 0
Step-by-step explanation:
The vertex of the parabola is at x=0. If values of x are included from both sides of the vertex, the function will not pass the horizontal line test. So, the domain must be limited so that it does not include both positive and negative values of x.
The domain could be x ≥ 0, or x ≤ 0, or some subset of either of these intervals.
Answer:
y + 1 = -14(x - 2)^2y = -14(x - 2)^2 - 1
Step-by-step explanation:
The function 
is a quadratic function due to the highest exponent being 2.
Given functions are:
<h3>What is a quadratic function?</h3>
A function of the form 
with 
is called a quadratic function means the highest exponent of polynomial should be 2.
Let us check one by one.
Highest exponent =2
The function is also of form so u(x) is a quadratic function.
The functions v(x), y(x), and z(x) are having highest exponents as 3,5, and 3 respectively so they are not quadratic functions.
Hence, the function is a quadratic function due to the highest exponent being 2.

Answer:
x=-2.25,y=-2.25
Step-by-step explanation:
The given system is
We want to solve the system for x and y that makes the system true.
Let us multiply the first equation by 3 while maintaining the second equation:
Subtract the current second equation from the first one.
Divide through by 12:
From the second equation we have:
This implies that:
