Please help? Graph <img src="https://tex.z-dn.net/?f=-3x%5E2%2B12y%5E2%3D84" id="TexFormula1" title="-3x^2+12y^2=84" alt="-3x^2+
mariarad [96]
-3x^2+12y^2=84
12y^2=3x^2+84
y^2=\dfrac{x^2}4+7
y=\pm\sqrt{\dfrac{x^2}4+7}

For either square root to exist, you require that \dfrac{x^2}4+7\ge0. This is true for all x, since \dfrac{x^2}4 is always non-negative. This means the domain of y as a function of x is all real numbers, or x\in\mathbb R or (-\infty,infty).

Now, because \dfrac{x^2}4+7 is non-negative, and the smallest value it can take on is 7, it follows that the minimum value for the positive square root must be \sqrt7, while the maximum value of the negative root must be -\sqrt7. This means the range is y\in\mathbb R\setminus(-\sqrt7,\sqrt7), or |y|\ge\sqrt7, or (-\infty,-\sqrt7]\cup[\sqrt7,\infty).

RJ solves a math problem on the whiteboard using the Powers of Products Property. Is his answer correct? Explain.
jeyben [28]
It’s A. Since every aspect of that is multiplication, you can change around how you write it such as (6*7)^3. 6*7 is 42, and 42^3 is the exact same as 42^3
