Which of the following equations represents a parabola that opens downward and has a vertex of \((4,-2)\)?
The quadratic function \(g(x)=3x^2+6x-9\) represents a parabola in the xy-plane. For what value of x does the value of \(g(x)\) reach its maximum or minimum?
A water fountain creates a parabolic arc of water. The height \(h(t)\), in feet, of the water from the fountain, \(t\) seconds after it is emitted, can be modeled by the function \(h(t)=-4{(t-5)}^2+20\). Which of the following is the best interpretation of the vertex of the graph of \(y=h(t)\) in the ty-plane?
The graph below represents a quadratic function. Which of the following equations matches the function shown in the graph?
A diver jumps from a cliff into the sea and her height above the water level over time can be modeled by the function \(h(t)=-16{(t-2)}^2+64\), where \(h(t)\) is the height in feet, and \(t\) is the time in seconds after the jump. Which of the following is the best interpretation of the vertex of the graph of \(y=h(t)\) in the ty-plane?
