End Behavior of Polynomial Functions

What is the end behavior as x → -∞ f(x)→ ?

• -∞
• ∞

What is the predicted end behavior of: y=-2x⁴+3x-1

• up on both ends
• down on both ends
• up on left, down on right
• down on left, up on right

Determine the end behavior of the polynomial by identifying the degree and leading coefficient.

f(x) = 5x⁴ - x + 6

• UP-UP

• UP-DOWN

• DOWN-UP

• DOWN-DOWN
