Intercepts & Zeros

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

• x-intercept

• zero

• root

• all of these.

• solution

^{What is the x- intercept of the line?}

• (0,-1)
• (-2,0)
• (-1,0)
• (0,-2)

Give the x-intercept
3x + 8y = 24

• (8, 0)
• (0, 8)
• (3, 0)
• (0, 3)

Determine the y-intercept for the following equation
4x + 2y = -12

• (0,-3)
• (0,-6)
• (-6,0)
• (-3,0)

What is the x and y intercept for the following equation ?
4x - 10y = 20

• x - int = 4    
  y-int = -10
• x-int = 5
  y-int = 2
• x - int = 5
  y int = -2
• x -int = 4
  y -int = -10

A zero of a function is essentially where the graph of the function intersects the x-axis. (True or False)

• True

• False

Name the zeros?

• (0, 0)

• (2, 4)

• (0, 0) and (0, 4)

• (0, 0) and (4, 0)

Give the y-intercept

• (2,0)
• (-2,0)
• (0,-2)
• there is no y-intercept
