The table below is a quadratic function.
<h3>What is a quadratic function?</h3>
A quadratic function is an Algebraic function with the power of its variable as 2.
This function normally has three algebraic terms, the x-square term, the x-term and the constant term.
Analysis:
The X-column values increases from -2 to 1, while the f(x) column which is the y-column increase from -9, until it gets to 1, where the value falls to -5.
A typical behavior of an inverted-v curve which is a quadratic curve.
If it were a linear function, as x values increase, y value would either keep increasing or decreasing, it does not change its orientation.

Answer:
The function domain is:
{x|x ≥ -4}
Hence, option 4 is correct.
Step-by-step explanation:
Given the expression of the function
We know that the domain of the function is the set of input values for which the function is real and defined
We know that the value inside the radical expression must be greater than or equal to 0 so that the function remains defined.
so
subtract 4 from both sides
simplify
Therefore, the function domain is:
{x|x ≥ -4}
Hence, option 4 is correct.
Answer:
D = 31
Step-by-step explanation:
Consider the equation showing the distributive property.
84 +93 = 3 (28+ D)
The unknown value we are asked to find is D
Hence:
84 + 93 = 84 + 3D
Collect like terms
84 - 84 + 93 = 3D
93 = 3D
D = 93/3
D = 31
Therefore, the unknown value that would make the equation true is 31
