Math Problem Statement

Gambarkan grafik fungsi y = x2 – 5x – 3 dan fungsi y = x – 2 dan tunjukkan titik potong kedua fungsi tersebut.

Solution

The graph of the functions y=x25x3y = x^2 - 5x - 3 (blue curve) and y=x2y = x - 2 (red line) shows two points of intersection. The coordinates of these points are approximately:

  1. (6.16,4.16)(6.16, 4.16)
  2. (0.16,2.16)(-0.16, -2.16)

These are the points where both functions intersect on the graph.

Here are five related questions to explore further:

  1. How do you find the intersection points algebraically?
  2. Can we find the tangent lines at the intersection points?
  3. What is the significance of the roots of a quadratic function?
  4. How does the graph of y=x25x3y = x^2 - 5x - 3 shift compared to y=x2y = x^2?
  5. How would the graph change if we modify the linear function y=x2y = x - 2?

Tip: Intersection points of two functions occur where the values of the functions are equal at the same xx. Solving the equation f(x)=g(x)f(x) = g(x) helps find these points.
