Answer:
{-3, 2, 3, 5}
Step-by-step explanation:
The <em>domain</em> of the inverse function is the <em>range</em> of the function. The y-values are already in numerical order: {-3, 2, 3, 5}.
4/3 of the area of the larger hexagon to the area of the smaller hexagon
Let the sides of the interior hexagon be 2 cm long, then this hexagon is made up of 6 equilateral triangles of side = 2.
The area of this hexagon = 6 * 1 * sqrt3 = 6 sqrt3 ( as the triangle is made up of 2 60-30-90 triangles)
The exterior hexagon is made up of 6 equilateral triangles with altitude 2 and the area = 6 * 2 * (2 / sqrt3 ) = 24 / sqrt3
area exterior hex / interior hex = 24 / sqrt3 * 1 / 6sqrt3 = 24/18
= 4/3
Required ratio = 4/3 answer

Answer:
(x + 3) ( x - 6)
Step-by-step explanation:
x² - 3x - 18
x² - 6x + 3x - 18
x(x - 6) + 3(x - 6)
(x + 3) ( x - 6)
twice means "multiply by 2"
increased means "add"
2n + 4 = 18
