How do you solve #x^2 - 2x - 24=0# graphically?

Answer 1

-4 and 6

To solve a quadratic equation graphically, we must know a few information: a. a > 0, the parabola opens upward b. The x-coordinate of the axis of symmetry, and the vertex: #x = -b/(2a) = 2/2 = 1#. c . The y-coordinate of vertex: y(1) = 1 - 2 - 24 = -25 --> vertex (1, -25) d. The y-intercept. Make x = 0 --> y = -24. graph{x^2 - 2x - 24 [-10, 10, -5, 5]} The graph gives 2 x-intercepts (real roots): -4 and 6.

To solve the quadratic equation x^2 - 2x - 24 = 0 graphically, plot the equation as a parabola on a graph, and find the x-intercepts, which represent the solutions.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
