WebDec 18, 2024 · The equation for a circle is (x −h)2 + (y −k)2 = r2, where (h,k) is the center and r is the radius. Plugging in 3 and −7 for h and k, we get (x −3)2 + (y + 7)2 = r2. Since you want the circle to be tangent to the y -axis, and we know that tangent refers to a line that touches something at exactly one point, we want the circle to have a ...

What is the tangent to the x-axis? - Quora
WebProblem 1. Find all points on the graph of y = x 3 - 3 x where the tangent line is parallel to the x axis (or horizontal tangent line). Solution to Problem 1: Lines that are parallel to the x axis have slope = 0. The slope of a tangent line to the graph of y = x 3 - 3 x is given by the first derivative y '. y ' = 3 x 2 - 3. WebThis is the discriminant and if it equals zero, the graph is tangent to the x-axis. So set this discriminant for your problem equal to zero and you have the equation: . . Multiply out the terms in parentheses and you get: . . Get rid of the -4 on the left side by adding 4 to both sides and you have: . WebMar 30, 2024 · If a graph is tangent to the x-axis, the graph touches but does not cross the x-axis at some point on the graph. The tangent of a circle always forms a 90 degree, or right angle, with the radius of the circle at that point. This tangent line is a geometric … readelf -ws
