To apply the Intermediate Value Theorem (IVT), we need to check two conditions:
1. The function, in this case, f(x) = 2x^3 - 2x^2 - 2x + 1, must be continuous on the interval [a, b].
2. The values of the function, f(a) and f(b), must lie on opposite sides of the x-axis. In other words, if f(a) is positive and f(b) is negative (or vice versa), then there exists at least one value c in the interval [a, b] such that f(c) = 0.
Let's start by checking the first condition: continuity. The given function, f(x) = 2x^3 - 2x^2 - 2x + 1, is a polynomial, and polynomials are continuous on their entire domain. Therefore, the first condition is satisfied.
Now, for the second condition, we need to find two values, a and b, such that f(a) and f(b) have opposite signs. One way to do this is by evaluating the function at various points within the desired interval. Since we do not know the exact solutions, let's try evaluating f(x) for some integer values within the interval [-2, 2]:
f(-2) = 2(-2)^3 - 2(-2)^2 - 2(-2) + 1 = 3
f(-1) = 2(-1)^3 - 2(-1)^2 - 2(-1) + 1 = -3
f(0) = 2(0)^3 - 2(0)^2 - 2(0) + 1 = 1
f(1) = 2(1)^3 - 2(1)^2 - 2(1) + 1 = -1
f(2) = 2(2)^3 - 2(2)^2 - 2(2) + 1 = 9
As we can see, f(-1) is negative, and f(0) is positive. Therefore, by the IVT, there exists at least one value c between -1 and 0 such that f(c) = 0.
To find the precise value of c, we can use a graphing calculator or computer grapher as suggested. By graphing the given equation, we can observe the x-intercept(s), which represent the solutions to the equation.
Using a graphing calculator or computer grapher, plot the equation y = 2x^3 - 2x^2 - 2x + 1. The x-intercept(s) on the graph represents the solutions to the equation.
Alternatively, you could solve the equation numerically using methods like Newton's method or the bisection method, which can be implemented using programming or specialized software.
Remember to check for any other possible solutions within the given interval or by considering additional conditions.
