to work it out just go output f (x) - input x so, 3 - 1 = 2 and double check this using your next equations 4 - 2 = 2
Answer: First, you identify how many rises and runs the line is from each point on a graph (intersection). Then you take the y's and the x's and do y2-y1/x2-x1 to get the slope!
Answer:
The other factor is 
Step-by-step explanation:
we know that


In this problem we have

and
-----> because is a factor
substitute and solve for b

so

Verify in the second equation

--> is ok
The other factor is 
Answer: not all
Step-by-step explanation:
Add 5+3 raised to the 2nd which givea u (8)^2
do the 5 squared which gives u 1+25-23
evaluate 8^2=64
subtract the sum u should get 64 over 3, 21 and 1/3 or 21.3333333 repeating
