Answer:
A
Step-by-step explanation:
The y intercept is simply where the line intercepts the y intercept in this case it's (0,2)
An easy way to slope is rise over run.
Simply find a point on the graph and count how many times you have to go up,down,left, or right to get to the next point
in this case it's 3
Since the slope is going down we know it will be negative.
Answer: 
Step-by-step explanation:
The exponential function will have this form:

We know that the function passes through the points
and
. Then, we can substitute the coordinates of the point
into
and solve for "a":

Then, we know that:

Now, we neeed to substitute the coordinates of the second point
into
and solve for "b":

Substituting the value of "b" into
we can find "a":

Therefore, we get that the exponential function that describes the graph, is:

Answer:
1920 yd³
Step-by-step explanation:
If there are parentheses you add the exponent on the outside to the exponents inside that belong to a variable.
For the three you would just cube it regularly, but for the x you would add the 3 to the 2 that is already on the x
