Question: Use a graphing utility to graph the equation and approximate any x-intercepts. Then set y = 0 and solve the resulting equation. Compare the result

Use a graphing utility to graph the equation and approximate any x-intercepts. Then set y = 0 and solve the resulting equation. Compare the result with the graph's x-intercept.
1. y = 2(x − 1) - 4
2. y = 4 / 3x + 2
3. y = 20 − (3x − 10)
