Determine the domain and range of the function f(x) = 2/1082x.
{x| all real numbers}; {yl y >0}
{x| all real numbers}; {yl y = 0}
O {x} x >0}; {yl all real numbers}
O {x| x2 0}; {yl all real numbers)

answer: 1475

step-by-step explanation:

becuase you have to know what they are asking you

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).

the answer is d

for problems like this theres an app, its photomath that explains the problem and gives the answer hope i
