Question

The height of a small rock falling from the top of a 124-ft-tall building with an initial downward velocity of –30 ft/sec is modeled by the equation h(t) = –16t2 – 30t + 124, where t is the time in seconds. Write the solution in interval notation for the length of time the rock was falling. Are these domain or range values? . Write down the answer and a helpful tip to help you remember how to solve these types of quadratic equations. 2. Solve by any method of your choosing: f(x) = 2x²+ 8x - 2 = 0. Write down the answer and a helpful tip to help you remember how to do solving by completing the square. 1. Solve by completing the square x²+x-12=0 Write down the answer and a helpful tip to help you remember how to do interval notation with domain and range.
