Consider the function: f(x)=3x2+30x72\displaystyle {f{{\left({x}\right)}}}=-{3}{x}^{{2}}+{30}{x}-{72}

The direction of the graph is like which of the following:





The y-intercept is at y=\displaystyle {y}=

The x-intercepts are at x=\displaystyle {x}=

The vertex is at the point

YOU SHOULD PRACTICE DRAWING THIS GRAPH ON YOUR OWN PAPER TO BE SURE IT LOOKS RIGHT!
