• 5x^-2 +3x - 1

• 2x⁵ + 3x⁴ + 2x³ + x² - 10

• 2x + 5

• 3

• 5

• 45

What is the leading coefficient?

Remember to look at your roots, multiplicity, and end behavior!!

Use your notes!

• Positive

• Negative

Based on the end behavior which option best describes the leading term?

Remember to look at your roots, multiplicity, and end behavior!!

Use your notes!

• negative coefficient, even degree

• negative coefficient, odd degree

• negative degree, odd coefficient

• negative degree, even coefficient

What is the end-behavior of the function shown by the graph?

If the degree of the function is even, then...

• The end arrows point in the same direction

• The end arrows point in opposite directions

• There is no way to tell what the ends of the graph do.

What is a possible equation in factored form of a function if it has zeros of 2, 3 and -1?

• y=(x-2)²(x-3)(x+1)³

• y=(x-1)⁶(x-2)(x-3)

• y=(x-1)(x+2)(2x+6)

• y=(x+1)(x+2)(x+3)
