(5v4+ 8v3) – (6v4 + 3v + 6v3)

  -v^4 +2v^3 -3v

Step-by-step explanation:

Perhaps you want to collect terms. You do this by combining coefficients of like terms. Like terms are ones with the same variable expression.

  (5v^4+ 8v^3) – (6v^4 + 3v + 6v^3)

  = 5v^4 +8v^3 -6v^4 -3v -6v^3 . . . . . . . distribute the minus sign

  = v^4(5 -6) +v^3(8 -6) +v(-3) . . . . . . . . . identify and group like terms

  = -v^4 +2v^3 -3v

step-by-step explanation:

just count the values of x & y of the vertex of the graph and see how many units in the x and y direction will get you from the f(x) graph to the f(x) graph
