Question

determine the concavity of the parabola representing the quadratic function it's y intercept is x-intercept if exist and the coordinates of the vertex and sketch the graph f(x) =25x2+8x-12​

Answer 1

Step-by-step explanation:

Now let us determine the vertex. The x-coordinate of vertex is. x 0 = − b ... Next we obtain the intersection point of the parabola and y- axis. ... We shoul solve an equation ... 25x2+8x−12 =0.
