Graph the function f(x) = x3 – 4x – 1. which are approximate solutions for x when f(x) = 0?

x = 1, √5, -√5

Step-by-step explanation:

Graphing of Function:

The given function will cut the y-axis at (0,-1) and it will cut the x-axis at (0,1),(0,√5), (0.-√5).

We are given the function f(x) =

We have to  approximate the solutions when f(x) = 0, that is,

f(x) = = 0

⇒

⇒

⇒ x = 1,

Now,

⇒

⇒ x = ±√5

Thus, x = 1, √5, -√5

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality
