- In the following exercises, solve 464. For the function f(x)=25x281 , find: (a) the zeros of the function (b) the x-intercepts of the graph of the function (c) the y-intercept of the graph of the function.arrow_forwardIn the following functions, find (a) the equation of the axis of symmetry and (b) the vertex of its graph. 239. f(x)=x2+2x+5arrow_forwardIn the following exercises, solve. 334. Gianna is going to throw a ball from the top floor of her middle school. When she throws the ball from 48 feet above the ground, the function h(t)=16t2+32t+48 models the height, h, of the ball above the ground as a function of time, t. Find: (a) the zeros of this function which tells us when the ball will hit the ground. (b) the time(s) the ball will be 48 feet above the ground. (c) the height the ball will be at t=1 seconds which is when the ball will be at its highest point.arrow_forward
- In the following exercises, solve. 444. Shruti is going to throw a ball from the top of a cliff. When she throws the ball from 80 feet above the ground, the function h(t)=16t2+64t+80 models the height, h, of the ball above the ground as a function of time, t. Find: (a) the zeros of this function which tells us when the ball will hit the ground. (b) the time(s) the ball will be 80 feet above the ground. (c) the height the ball will be at t=2 seconds which is when the ball will be at its highest point.arrow_forwardIn the following exercises, solve. Round answers to the nearest tenth. 282. A retailer who sells backpacks estimates that by selling them for x dollars each, he will be able to sell 100x backpacks a month. The quadratic function R(x)=x2+100x is used to find the R, received when the selling price of a backpack is x. Find the selling price that will give him the maximum revenue, and then find the amount of the maximum revenue.arrow_forwardIn the following exercises, solve. 333. Juli is going to launch a model rocket in her back yard. When she launches the rocket, the function h(t)=16t2+32t models the height, h, of the rocket above the ground as a function of time, t. Find: (a) the zeros of this function which tells us when the rocket will hit the ground. (b) the time the rocket will be 16 feet above the ground.arrow_forward
- In the following exercises, solve. Round answers to the nearest tenth. 281. A computer store owner estimates that by charging x dollars each for a certain computer, he can sell 40x computers each week. The quadratic function R(x)=x2+40x is used to find the revenue, R, received when the selling price of a computer is x, Find the selling price that will give him the maximum revenue, and then find the amount of the maximum revenue.arrow_forwardIn the following exercises, for each function, find: (a) the zeros of the function (b) the x-intercepts of the graph of the function (c) the y-intercept of the graph of the function. 320. f(x)=12x211x+2arrow_forwardIn the following exercises, solve. Round answers to the nearest tenth. 279. A ball is thrown vertically upward from the ground with an initial velocity of 109 ft/sec. Use the quadratic function h(t)=16t2+109t+0 to find how long it will take for the ball to reach its maximum height, and then find the maximum height.arrow_forward
