Answer: a: -2, b: 0
Step-by-step explanation:
f(2) means that x=2, and we need to solve for y.
On the graph, it has a point of (2, -2) and since it's a function that is the only possible output. Therefore, f(2)=-2.
f(x)=-4 means that y=-4, and we need to solve for x.
On the graph, the point (0,-4) exists, and since the function contains only one output, it must be correct. Therefore, x=0.
C because if it was constant then for day 3 the distance would be 65.4 instead of 64.8
Subtract any number from the next one.
-1 - (-6)
4 - (-1)
9 - 4
14 - 9
All of the above subtractions give the same answer.
That answer is the common difference.

1/6
FIRST
12 IS THE LOWEST COMMON DENOMINATOR
SECOND
1\3
4/3
=-5/12
THIRD 3 -5/12
= -2/12
=1/6
To find the unit rate, you would do 2.99 / 11.3 and get about 26 cents. So the unit rate would be 26 over 1 ( 26/1 ).
