- Evaluate the function.arrow_forwardShow workarrow_forwardThe total, C to attend a swim meet for a swimmer competing in x events can be modeled using a linear function. Each swimmer will pay a $3.00 entry fee for each event a $8.75 for lunch. Each swimmer may sign up for a maximum of 5 events. What are the domain and range of the function for this situation? A. Domain:{ 11.75, 14.75, 17.75, 20.75, 23.75} , Range: { 1,2,3,4,,5} B. Domain All real numbers greater than or equal to 1 and less than or equal to 5. Range: All real numbers greater than or equal to 11.75 and less than or equal to 23.75 C. Domain: { 1, 2, 3, 4, 5}, Range: { 11.75, 14.75, 17.75, 20.75, 23.75} D. Domain: All real numbers less than or equal to 5. Range: All real numbers less than or equal to 23.75.arrow_forward
- A movie theater is offering a special summer pass. Passholders pay $8 per movie for the first 5 movies and watch additional movies for free, up to a maximum of 15 movies. The function C gives the total cost, in dollars, for a passholder to watch n moves.arrow_forwardw later The publisher of a medical newsletter estimates that with x thousand subscribers its monthly revenue can be modeled by the function, R(x) = 60,000x - 50x and cost (in thousands of dollars) is modeled by the function C(x) = x+ 100x + 800. Write the function, in standard form, to represent the medical newsletter's profit, P(x), if P(x) = R(x) -C(x). %3D A- O Varrow_forwardUse the graph of the function f, shown in Figure ,to find (a) the domain of f,(b) the function values f(−1) and f(2), and (c) the range of f.arrow_forward
- Find the domain of the function. f(x)=4x+4+8x−14 What is the domain of f? A. (−∞,−4)∪(−4,∞) B. (−∞,−4)∪(−4,14)∪(14,∞) C. (−∞,0)∪(0,∞) D. (−∞,∞)arrow_forwardInspect the graph of the function to determine whether it is concave up, concave down or neither, on the given interval. A cube function, m(x) = - 4x³, on (-∞,0) On the interval (-∞,0), the function m(x) = − 4x³ is concave down. neither concave up or concave down. concave up.arrow_forwardThe cost C, in dollars, to tow a car is modeled by the function C ( x ) = 5 x + 80 where x is the number of miles towed. If the cost of towing a car is $95, how many miles was it towed? Group of answer choices It was towed 16 miles. It was towed 5 miles. It was towed 555 miles. It was towed 3 miles. It was towed 80 miles.arrow_forward
