Finding a point on a parabola
WebJan 16, 2024 · Recognizing Characteristics of Parabolas. The graph of a quadratic function is a U-shaped curve called a parabola. One important feature of the graph is that it has an extreme point, called the vertex.If the parabola opens up, the vertex represents the lowest point on the graph, or the minimum value of the quadratic function. If the parabola … WebDec 28, 2024 · Thus parametric equations for the parabola y = x2 are x = t / 2 y = t2 / 4. To find the point where the tangent line has a slope of − 2, we set t = − 2. This gives the point ( − 1, 1). We can verify that the slope of the line tangent to the curve at this point indeed has a slope of − 2.
