You have to post a picture of the actually histogram we can’t see it
B. both r correct
when it’s 2x it goes up two over one. rise/run, 2/1
for the table if you look at the graph when x=1 then y=2 and if x=2 then y=4
The domain of a function are the possible input values of the function.
<em>The domain of the function is (d) Whole numbers</em>

We have:

The graph has no end; so:

This means that the domain of the graph is 
The number of times one can visit the pool cannot be decimal.
Hence, the domain of the function is whole numbers

Sum of complementary angles = 90
so
5x + 35 = 90
5x = 90 -35
5x = 55
