The Deep Dive
Did you know that the equation \( y=-3x^2+12x+2 \) represents a downward-opening parabola? This is due to the negative coefficient of the \( x^2 \) term, which gives it a "frown" shape. Among the many properties of parabolas, the vertex represents either a maximum or a minimum point—in this case, it’s the maximum since our parabola opens downward. To find the vertex, you can use the vertex formula \( x = -\frac{b}{2a} \). Plugging in values from our equation where \( a = -3 \) and \( b = 12 \), you'll discover that the x-coordinate of the vertex is at 2. After substituting back into the equation, you can find the maximum y-value to complete your parabolic journey. Happy graphing!
