Use the parabola tool to graph the quadratic function f(x)=−5x^2−2. Graph the parabola by first plotting its vertex and then plotting a second point on the parabola. help

Heather is writing a quadratic function that represents a parabola that touches but does not cross the x-axis at x = -6. which function could heather be writing? fx) = x2 + 36x + 12 = x2 - 36x - 12 f(x) = -x + 12x + 36 f(x) = -x? - 12x - 36
