The Function having highest Degree of Four given here is :
As the given function has highest degree of four, it has maximum of four roots.
As complex and Irrational root occur in pairs, so There are many possibilities
1. Two Complex or Irrational + Two Real
2. Four real roots
3.All roots are complex or irrational
By looking at the options described below, it means it has four real roots.
It will cut X axis at four points.
With the help of Desmos you can directly find the solution of this problem, but without desmos Graphing, we first have to check by Taking different points on the curve whether graph of function described here is correct or not, i.e by method of increasing and decreasing formula of a function.The method to check is
If there are two points on the curve i.e 
1. 
Increasing Function.
2. 
Decreasing Function.
Option (4) is true .
Answer:
x = 5
Step-by-step explanation:
because the log is base 2 you can remove the log by raing 2 to the power of each side:
the 2 and log2 cancel leaving:
this means we can now solve through simple algebra:
Answer:
10 ≥ w ≥ 9 ( ? )
Step-by-step explanation:
the probability that a Great blue heron is at least 9 pounds, but no more than 10 pounds -> w= weight of great blue heron
w is at lest 9 pound's -> w ≥ 9
w is no more than 10 pound's -> w ≥ 10
w ≥ 9 ( + ) w ≥ 10 = 10 ≥ w ≥ 9
Based on the definition of <em>composite</em> figure, the area of the <em>composite</em> figure ABC formed by a semicircle and <em>right</em> triangle is approximately 32.137 square centimeters.
<h3>How to find the area of the composite figure</h3>
The area of the <em>composite</em> figure is the sum of two areas, the area of a semicircle and the area of a <em>right</em> triangle. The formula for the area of the composite figure is described below:
A = (1/2) · AB · BC + (π/8) · BC² (1)
If we know that AB = 6 cm and BC = 6 cm, then the area of the composite figure is:
A = (1/2) · (6 cm)² + (π/8) · (6 cm)²
A ≈ 32.137 cm²
Based on the definition of <em>composite</em> figure, the area of the <em>composite</em> figure ABC formed by a semicircle and <em>right</em> triangle is approximately 32.137 square centimeters.
