Graph the function f(x) = x3 – 4x – 1. which are approximate solutions for x when f(x) = 0? check all that apply. –2.11 –1.86 –0.25 0.25 1.86 2.11

-1.86, -0.25 and 2.11

Step-by-step explanation:

In the figure  attached a plot of the function is shown. The solutions for x when f(x) = 0 are also given.

To check if a given x is solution of f(x) = 0, just replace x value in the formula and verify if the function is or not equal to zero.

x           f(x)

-2.11      (-2.11)^3 - 4(-2.11) -1 = -1.95

-1.86     (-1.86)^3 - 4(-1.86) -1 ≅ 0

-0.25    (-0.25)^3 - 4(-0.25) -1 ≅ 0

0.25     (0.25)^3 - 4(0.25) -1 = -1.98

1.86      (1.86)^3 - 4(1.86) -1 = -2

2.11       (2.11)^3 - 4(2.11) -1 ≅ 0

Therefore, the solutions are: -1.86, -0.25 and 2.11

oof cheaters cheat because they’re lazy that’s why i cheat xd

step-by-step explanation:

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
