Choose the end behavior of the graph of each polynomial function. f(x) = -5x+ + 2x3 + 3x + 1

A) Falls to the left and rises to the right.
B) Rises to the left and falls to the right.
C) Rises to the left and rises to the right.
D) Falls to the left and falls to the right.​

Replace w with 10 and solve for a:

10 = (a-7000/2000 + 2)

Subtract 2 from both sides:

8 = a-7000 /2000

Multiply both sides by 2000:

16,000 = a-7000

Add 7000 to both sides:

a = 23,000

You can climb 23,000 feet

The explanation is replacing w with the number of weeks ( 10) and solving for a. You can then check by replacing a with the solution and solving for w.
