Given y=2s^2-8x+4    a.  Complete the square to convert to vertex form  (y=a(x-h)^2+k) b. find the roots and sketch function

Determine the x-intercepts of the following parabola: f(x) = = −3x² + 18x − 1. Write intercepts as ordered pairs with no spaces, round to two decimal places, and only one intercept per blank. Hint: one intercept is (.06,0). A 신

The flight path of a rocket, launched from the ground, is modeled by y = 0.25(40x-x²), where y is the height of the rocket in feet from the ground and x is the time in seconds after it was launched. Find the vertex of the parabola and explain what it represents in terms of the context. O (40, 0); rocket lands at 0 feet after 40 seconds O (20, 100); rocket reaches maximum height of 20 feet after 100 seconds O (40, 0); rocket reaches 40 feet after 0 seconds O (20, 100); rocket reaches maximum height 100 feet after 20 seconds
