Calum is going to throw his lucky penny from his balcony on a cruise ship. When he throws the penny upward from 128 feet above the ground, the function h(t) = −16t2 + 32t + 128 h(t) = −16t2 + 32t +128models the height, h, of the penny above the ocean as a function of time, t. Find: a. the zeros of this function which is when the penny will hit the ocean b. when the penny will be 128 feet above the ocean. c. the height the penny will be at t = 1 second which is when the penny will be at its highest point

Graph the function and please give me a table of values so that I can graph.

For the given function, find each of the components. You will upload a picture of your work (not just the answer show how you got the answer); be sure that it is neat and clearly labeled. f(x)=x2−3x−7f(x)=x2-3x-7 a. Find the vertex. b. Find the x-intercepts and write as an ordered pair. c. Find the y-intercept and write as an ordered pair. d. Find the equation of the axis of symmetry. e. Sketch the graph of the function using at least 5 points. 5 points must be identified to receive full credit.

The height of Jocelyn's rocket, in feet, as a function of time, in seconds, is modeled by the equation J(t)=-16t^2+180t. The height of Kelly's rocket, in feet, as a function of time, in seconds, is modeled by the equation K(t)=-16t^2+240t. a. Evealuate J(3)  b. Who would win a rocket launching contest by having the highest flying rocket? c. How much more time did it take for the second rocket to hit the ground? d. If we launch Kelly's rocket from a height of 12 feet how does that change Kelly's function K(t)?

x2 + 6x + 8, 7. For the graph of the function f(x) A. Write the function in standard form: B. find the vertex; C. x-intercepts D. y-intercepts E. Graph the function
