Step 1: Understand the problem. To solve the equation 2x^3 - 3x^2 - 12x + 5 = 10 using the graph, you need to find the x-values where the curve y = 2x^3 - 3x^2 - 12x + 5 intersects the horizontal line y=10. Step 2: Identify the intersection points from the graph (or the table of values used to create the graph). We look for x-values where y=10. Using the table of values: | X | -3 | -2 | -1 | 0 | 1 | 2 | 3 | 4 | |---|----|----|----|---|---|----|---|---| | Y | -40| 1 | 12 | 5 | -8| -15| -4| 37| • The first intersection occurs between x=-2 (where y=1) and x=-1 (where y=12). Since 1 < 10 < 12, there is a solution in this interval. Estimating from a graph, this value is approximately x ≈ -1.2. • The second intersection occurs between x=-1 (where y=12) and x=0 (where y=5). Since 5 < 10 < 12, there is a solution in this interval. Estimating from a graph, this value is approximately x ≈ -0.7. • The third intersection occurs between x=3 (where y=-4) and x=4 (where y=37). Since -4 < 10 < 37, there is a solution in this interval. Estimating from a graph, this value is approximately x ≈ 3.3. The solutions to 2x^3 - 3x^2 - 12x + 5 = 10 from the graph are approximately: x ≈ -1.2, x ≈ -0.7, x ≈ 3.3 The solutions are x ≈ -1.2, -0.7, 3.3.
