Q. What is the focus of the parabola y=4x2?Simplify any fractions.(______,______)
Identify Orientation: Identify the orientation of the parabola.Since the equation is y=4x2, it's a vertical parabola.
Write in Vertex Form: Write the equation in vertex form to find a, h, and k. The equation y=4x2 is already in the form y=a(x−h)2+k with a=4, h=0, and k=0.
Calculate Value of p: Calculate the value of p using the formula p=4a1. p=4×41p=161
Find the Focus: Find the focus using the values of h, k, and p. The focus is at (h,k+p) which is (0,0+161).
