The graph that shows y=3⌈x⌉ + 1 from the given options is the<u> Third graph </u>as shown attached.
<h3>Which graph shows the function best?</h3>The third graph shows the function and this can be tested as follows:
When x = 2, y = 7:
y = 3x + 1
= 3 x 3 + 1
= 7
When x = 3, y = 10:
y = 3 x 3 +1
= 10
When x = 1, y = 4
y = 3 x 1 + 1
= 4
This shows that the line on the third graph is well represented by the function, y=3⌈x⌉+1.

At 900 miles, the cost for the two rentals will be same.
Step-by-step explanation:
Given,
A+ Auto rental: $175 plus $0.10 per mile
Let,
x be the number of miles.
y be the total distance.
y = 0.10x+175 Eqn 1
Zippy Auto rental: $220 plus $0.05 per mile
y = 0.05x+220 Eqn 2
When Eqn 1 = Eqn 2, the cost will be same
Therefore;
Dividing both sides by 0.05
At 900 miles, the cost for the two rentals will be same.
