A quadratic function would fit this data.
The data does not increase at the same rate each time, so it is not linear. It comes to a maximum at (8, 150) and decreases. It decreases the same way it increased. This would lead to a U-shaped graph, which indicates a quadratic function.
Answer:
Imagine the function y = absolute value(x). It looks like the English letter "V". The bottom of our V (i.e f(x) touches the x-axis when x = 6, so the "V" graph has been translated 6 units to the right of the origin. But when x = 6 the value of f(x) is 0-4 = -4 so the tip of the V is located 4 units below the x axis. Summary: g(x) looks like the absolute value function but is translated 6 units to the right of the origin and 4 units down
Step-by-step explanation:
498-53=445
445/2=222.5
222.5+53=275.5
so there were 222.5 student tickets sold
to check: 275.5 + 222.5+498
Multiply both sides by 30, to get rid of fractions... 12 + 30m = 25, subtract both sides by 12... 30m = 13. Divide both sides by 30, m = 13/30
