What are the zeros of the function?

• 4,1
• 3,1,-2,-5
• -3, -1, 2, 5
• -2,4

Identify the zeros:

• x=-2, x=-1, x=0
• x=-2, x=0
• x=-1, x=0, x=2
• x=-2, x=0, x=1

Solve the following equation. x⁴ + 4x³ + 3x² = 0

• x = 0, x = 3, x = 1

• x = -3, x = -1

• x = 3, x = 1

• x = 0, x = -3, x = -1

Solve (x²-9) = 0

• x = 9

• x = 9, -9

• x = 3, -3

• x = 3

What is another way to say "where a function crosses the x-axis"?

• x-intercept
• zero
• root
• all of these.
