Answer:

B. 5x^4+5x^3

Step-by-step explanation:

(f.g)(x) = f(x) * g(x)   = 5x^3 * (x+1)

          = 5x^3  * x + 5x^3  * 1

          = 5x^4 + 5x^3

This is a continuous set of points in the coordinate plane. It can be, but is not always, straight.

Answer:

Linear. While all linear equations produce straight lines when graphed, not all linear equations produce linear functions. In order to be a linear function, a graph must be both linear (a straight line) and a function (matching each x-value to only one y-value).

hmmm, between the three options I would go with the second one since the number of 1-foot cubes equals exactly the volume of the fish tank.

But to truly calculate the volume

5 x 3 = 15

15 x 3 = 45

45 is the volume of the fish tank
