Q. What is the focus of the parabola y=−3x2?Simplify any fractions.(______,______)
Identify Parabola Orientation: Identify the orientation of the parabola.Since the equation is y=−3x2, it's a vertical parabola.
Find Values of a, h, k: Find the values of a, h, and k. The equation y=−3x2 can be rewritten as y=−3(x−0)2+0. So, a=−3, h=0, and h0.
Calculate Value of p: Calculate the value of p using the formula p=4a1.p=4(−3)1p=−121
Determine Parabola Focus: Determine the focus of the parabola using the values of h, k, and p. The focus is at (h,k+p). So, the focus is at (0,0+(−121)).
Write Focus Coordinates: Write the coordinates of the focus.The focus of the parabola is (0,−121).
