Parabolas (5.1 - 5.3 Review) Weekly Quiz #26

Graph a PARABOLA with zeros at x = -3 and x = 5 & a MINIMUM at y = - 4.

The ​ (a)   is the point that touches the x-axis, whereas the ​ (b)   is the point that touches the y-axis.

Also, the imaginary line that touches the parabola is called the ​ (c)   .

• x-intercept
• y-intercept
• axis of symmetry

The axis of symmetry crosses this point: (a)  

The HIGHEST point of a parabola is called: ​ (b)   . The Minimum is the ​ (c)   point of a parabola.

• Vertex
• Maximum
• lowest

The graph shows the # of mosquitoes & rainfall (in cm.)

Identify:

1. 1. the INITIAL height of mosquito population

2. 2. After how many cm will mosquitoes equal "0" (Hint: GROUND)

• Initial Height: 4 million

  Rain cm: After 0 and 4 cm

• Initial Height: 0 million

  Rain cm: Only 0 cm

• Initial Height: 0 million

  Rain cm: After 0 and 4 cm

• Initial Height: 2 million

  Rain cm: After 4 cm
