Answer:
The function graphed is f(x) = 3x + 1
See that the y=intercept is at (0,1). That's where the +1 comes from.
Note that the graph goes up 3 spaces every time it goes 1 to the right. 3/1 = 3 is the slope.
The answer to 12 is C.
The answer to 13 is B. Neither is a function. For a function of x to exist, for every x, there must be only one y. In both tables, there's a number for x that gives two different y's.

Answer:
the answer to this question is D.
Answer:
When adding polynomials you've got to combine all like terms
2u^3 + 7u^3= 9u^3 (They both are raised to the third with the same variable.)
6u^2 (Stays the same because there are no other numbers that are raised to the second)
-7u (Again there are no other numbers to combine this with)
2+4=6 (Add 2+4 as normal)
Now you put together all the numbers that are left for your final answer
9u^3+6u^2-7u+6
Hope this helps ;)
