- The height h of a projectile is a function of the time t it is in die air. The height in feet for t seconds is given by the function h(t)=-16t2+96t . What is the domain of die function? What does the domain mean in the context of die problem?arrow_forwardFind the domain of the function: f(x)=5x+x3 .arrow_forwardCliff divers The height s, in feet, of a cliff diver is a function of the time t in seconds he has been falling. If s as a function of t can be expressed as st=-16t2+10t+300, what is the height of the diver at 3 seconds?arrow_forward
- Target heart rate The target heart rate f(x), in beats per minute, at which a person should train to get an effective workout is a function of the persons age x in years. If f(x)=0.6x+132, find the target heart rate for a 45-year-old college professor.arrow_forwardThe circumference C of a circle is a function of its radius given by C(r)=2r. Express the radius of a circle as a function of its circumference. Call this function r(C) , Find r(36) and interpret its meaning,arrow_forwardFind f(1) and f(2). f(x)=xx1arrow_forward
- A ball is thrown in the air from the top of a building.Its height, in meters above ground, as a function of time, in seconds, is given by h(t)=4.9t2+24t+8. How long does it take to reach maximum height?arrow_forwardPrinting Cost A publisher estimates that the cost C(x) of printing a run of x copies of a certain mathematics textbook is given by the function C(x)=5000+30x0.001x2 . (a) Find C(1000) and C(10,000) . (b) What do your answer in part (a) represent? (c) Find C(0) . What does this number represent? (d) Find the net change and the average rate of change of the cost C between x=1000 and x=10,000 .arrow_forwardRate of Change for a Linear Function If f is the linear function f=7x3, what is the value of dfdx?arrow_forward
