The equation of quadratic function is given below:
f(x) = 4x² 8x+3
Determine the vertex coordinates, the discriminant of the function, the -intercept(s) and y-intercept(s) that the parabola has. Choose the correct answer.
a. Vertex = (1,-1), discriminant = 4, the x- intercepts = (4,0) and (8, 0), and y-intercepts = (0,8).
b. Vertex = (1,-1), discriminant = 16, the 2- intercepts = (0.5, 0) and (1.5, 0), and y- intercepts = (0; 3).
c. Vertex = (0.5, 1.5), discriminant = 137, the x- intercepts = (1, -1) and (0, 0), and y-intercepts = (0, 4).
d. Vertex = (8, 4), discriminant = 112, the 2- intercepts = (0, 1.5) and (0, 0.5), and intercepts = (3, 0).
