How do you find the vertex and intercepts for #f(x) = 10x^2 - 5x + 12#?
x - coordinate of vertex:
y-coordinate of vertex:
y-intercept when x = 0, --> f(0) = 12
x- intercepts when f(x) = 0. Solve the quadratic equation:
There are no x-intercepts. The graph of f(x) is an upward parabola (a > 0), that completely stays above the x-axis.
