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.
c. 0.5x3 − 4 = 3x + 1

Answer 1

Answer: x = 3.05

Explanation:

The picture shows the graphic solution using technology.

Verifying the approximate solution found on the graph.

x = 3.05

0.5x³ - 4 = 3x + 1

0.5(3.05)³ - 4 = 3(3.05) + 1

0.5*28.373 - 4 = 9.2 + 1

14.2 - 4 = 10.2

10.2 = 10.2 (ok)
