Question

Find the approximate solution(s) to each of the following equations graphically. Use technology to support your

work. Verify the solution sets using the original equations.
b. x + 2 = x3 − 2x − 4

Answer 1

Answer: x = 2.36

Explanation:

Graphic solution is attached.

approximate solution is 2.36 according to the graph

Verifying the solution as asked:

x + 2 = x³ - 2x - 4

2.36 + 2 = 2.36³ - 2*2.36 - 4

4.36 = 13.14 - 4.72 - 4

4.36 ≈ 4.42

If we round to 4.4 it's clearer that this is the right solution.
