Answer:
Think about what domain and range is. Domain is the x and range is the y.
Step-by-step explanation: What values of x can you put in this function? Is there any number you cannot use?? Then what y's will you get back? The best way to find out might be to graph it to look. Since it is an even function whose ends go up, all the y's will be greater than or equal to the y value of the vertex.
We need a denominator in order to put this into a percentage. Unless the denominator is one, in which we can say 666.6666666... percent.
Answer: 14 tickets weren't sold.
Step-by-step explanation:
14 times 15 = 210
So there are 210 seats in the cinema.
The total is $1274 so you would divide
which equals 196
Your final step is to subtract
210 (the total seats) minis 196 (seats sold) equals 14 seats not sold
