Q. What is the focus of the parabola y=−10x2?Simplify any fractions.(______,______)
Identify Orientation: Identify the orientation of the parabola. Since the equation is y=−10x2, it's a vertical parabola.
Find Values: Find the values of a, h, and k from the equation y=−10x2.Comparing with y=a(x−h)2+k, we get a=−10, h=0, and k=0.
Calculate p: Calculate the value of p using the formula p=4a1.p=4(−10)1=−401.
Determine Focus: Determine the focus of the parabola using the values of h, k, and p. The focus is at (h,k+p), so it's (0,0−401) which simplifies to (0,−401).
