First, graph \(y=2x^2\) Since, the inequality sing is \(>\), we need to use dash lines Now, choose a testing point inside the parabola Let's choose \((0,2)\) \(y>2x^2→2>2(0)^2→2>0\) This is true So, inside the parabola is the solution section Exercises for Graphing Quadratic inequalities Sketch the graph of each function \(\colorAG5 Graphing Quadratic Functions Investigate and generalize how changing the coefficients of a function affects its graph 1 Which quadratic function is shown in the accompanying graph? Short demo on graphing a parabola by finding the vertex and yintercept, and using the axis of symmetry
Remember the vertex form of a parabola is y = a ( x − h) 2 k y=a (xh)^2k y = a ( x − h) 2 k, where ( h, k) (h,k) ( h, k) is the vertex We know that a = − 1 / 2 a=1/2 a = − 1 / 2 and we can read the vertex from the graph The vertex is ( 3, 4) (3,4) ( 3, 4) So we know h = 3 h=3 h = 3 and k = 4 k=4 k = 4Say we have the equation Yk=x^2 To see how this shifts the parapola up k units, substitute x with 0 The equation will simplify to yk=0 So for the equation to be true y needs to be equal to k;Answer by ewatrrr () ( Show Source ) You can put this solution on YOUR website!
