Answer:
y=20 + 10x
Step-by-step explanation:
Y=balance
the science cub started with 20 dollars, the first number. They gained 10 dollars a week, x, so the answer would be b.

Answer:
Step-by-step explanation:
False f(x) is not a function as there are multiple solutions for f(6.5)
True f(4) = 225
True f(a) = 50 has no solution as we are given no information as to what "a" is.
Even f(x) = 50 has no solution in the domain provided
False f(1) = 250
False f(100) is beyond the domain of the plot. Even if the plot repeats, it never gets down to 6.5...and how does one end up with a half a can, anyway?
False The plot never intersects the x axis
True F(0) = 250
True Seems to me the graph is a tell-all...not being discrete at all
(Joke) :)
Actually the graph lines are not correct. The data is number of cans, plotted against time. While time is continuous, cans must be sold in units. The plot points are valid, but the lines between them are just wishful thinking. If we ignore the lines, the plot is discrete.
True There are 300 cans in the machine at 1:30 pm
False 0 ≤ t ≤ 12 hrs is the domain
True f(10) = f(12) and all points between them have a value of 250
True graph slopes from f(2) to f(6.5) have negative values.
