Answer

Points of intersection: (0.2, 1.9), (4.6, -0.3), (0.7, 1.7) (rounded to nearest tenth) Explanation 1. Set the equations equal f(x) = g(x) gives -0.5x + 2 = x^3 - 5x^2 + 3. 2. Rearrange into a polynomial equation x^3 - 5x^2 + 0.5x + 1 = 0. 3. Use numerical methods to find roots Solve x^3 - 5x^2 + 0.5x + 1 = 0 using numerical methods (e.g., Newton's method or graphing calculator). 4. Calculate intersection points Find x values where f(x) = g(x), then calculate corresponding y values using either function.

Explanation

1. Set the equations equal<br /> $f(x) = g(x)$ gives $-0.5x + 2 = x^3 - 5x^2 + 3$.<br /><br />2. Rearrange into a polynomial equation<br /> $x^3 - 5x^2 + 0.5x + 1 = 0$.<br /><br />3. Use numerical methods to find roots<br /> Solve $x^3 - 5x^2 + 0.5x + 1 = 0$ using numerical methods (e.g., Newton's method or graphing calculator).<br /><br />4. Calculate intersection points<br /> Find $x$ values where $f(x) = g(x)$, then calculate corresponding $y$ values using either function.
