22 Find the Vertex of y = x 2 2x2 Parabolas have a highest or a lowest point called the Vertex Our parabola opens up and accordingly has a lowest point (AKA absolute minimum) We know this even before plotting "y" because the coefficient of the first term, 1 , is positive (greater than zero)Y=x^22x3 the easiest way is to use a table of values you can pick a few numbers for x, plug them in and solve for ySOLUTION Graph the equation y = 2x 3 on a coordinate plane You can put this solution on YOUR website!
Y= x^2 2x Solved by pluggable solver SOLVE quadratic equation (work shown, graph etc) Quadratic equation (in our case ) has the following solutons For these solutions to exist, the discriminantLet R be the region enclosed by y=x^2 and y=2x3 a) Set up a double integral (or double integrals) with the order of integration as dydx which represents the area of R b) Set up a double integral (or double integrals) with the order of integration as dxdy which represents the area of R y=1/2x4 We have, y = x^2 2x 3 To get the gradient of the tangent at any particular point we need the first derivative So, dy/dx = 2x2 The tangent at (2,3) will have the gradient given by dy/dx with x=2 x=2 => dy/dx=(2)(2)2 = 2 Therefore, The tangent to the parabola at (23) has gradient 2 The line that we seek is perpendicular to this tangent, and so the product
