Since we have a square, the triangle has sides: x, 6, and 3.
Using Pythagoras' Theorem, we get:
x² = 6² + 3²
x² = 36 + 9
x² = 45
x = √45 = 3√5
The range of the function y = -x² - 3x when the domain is {-5,0,2} is:
{-10, 0}.
<h3>What is the range of a function?</h3>
The range of a function is the set that contains the output values for the given domain of the function.
In this problem, the domain is:
{-5,0,2}.
Hence the output values are:
- -(-5)² - 3(-5) = -25 + 15 = -10.
- -(2)² - 3(2) = -4 + -6 = -10.
Hence the range is:
{-10, 0}.
-10 repeats, but goes only once on the range.

<u>Answer:</u>
- The x coordinate is known as <u>abscissa</u><u> </u><u>(</u><u>B)</u>
<u>Step-by-step</u><u> Explanation</u><u>:</u>
In a Cartesian plane, we learn many such terms which represent a point, or a line, or cooridnates of some points etc
Such terms are:
- Origin (Intersection of x axis and y-axis.)
- x - axis (Horizontal line)
- y - axis (Vertical line)
- abscisaa (x -coordinate)
- ordinate (y - coordinate)
Put this into an equation. Make the missing value "x".
6x - 5 = 49
49 + 5 = 54
54 / 6 = 9
x = 9.
The missing number is 9.
Hope This Helps You!
Good Luck Studying :)
