Answer:
The approximate solution for f(x)=g(x) is x= -1.
Step-by-step explanation:
Given two functions are f(x) and g(x)
f(x)= ![2 \;multiplied \;by \;x\; plus 1](https://tex.z-dn.net/?f=2%20%5C%3Bmultiplied%20%5C%3Bby%20%5C%3Bx%5C%3B%20plus%201)
Therefore, f(x)= 2x+1
g(x)=![x\; cubed\; plus \; 2\; multiplied\; by \; x \; squared \; minus \; x\; minus2](https://tex.z-dn.net/?f=x%5C%3B%20cubed%5C%3B%20plus%20%5C%3B%202%5C%3B%20multiplied%5C%3B%20by%20%5C%3B%20x%20%5C%3B%20squared%20%5C%3B%20minus%20%5C%3B%20x%5C%3B%20minus2)
Therefore, g(x)= ![x^3+2x^2-x-2](https://tex.z-dn.net/?f=x%5E3%2B2x%5E2-x-2)
From the given graph we can see that two functions are intersect to each other at points (1.46, 3.92) , ( -0.76, -0.52) and ( -2.7,-4.3).
It means the graph of two functions intersect at
x=1.46
x= -0.76
x=-2.7
The approximate value of
x=1.46=1.5
x=- 0.76=-1
x=-2.7=-3
Hence, f(x)=g(x) at x=-1
<h3>Therefore , the approximate solution is x= -1 for f(x)=g(x) </h3><h3>Hence, option C x=-1 is correct answer.</h3>
Check the picture below.
thus the rectangular coordinates are [ 11cos(-80°), 11sin(-80°) ].
make sure your calculator is in Degree mode.
