MODELING REAL LIFE A baseball is thrown up in the air. The table shows the heights $y$ (in feet) of the baseball after $x$ secon
nikklg [1K]

The equation for the path of the ball can be measured using a regression model calculator which produced the quadratic model ;

  • y(x) = - 16x² + 36x + 4
  • Height at x = 1.7 = 18.89 feets

<u>The table given</u> :

Time, x : __0.5 ___ 1 ____ 1.5 ____ 2

Height, y _ 18 ____22 ___ 24 ____ 12

<u>Using </u><u>technology</u><u> such as a </u><u>quadratic regression</u><u> calculator or </u><u>excel</u> ;

The quadratic regression model obtained is :

  • y(x) = - 16x² + 36x + 4

<u>The </u><u>height after, 1.7 seconds</u><u>, x = 1.7 can be calculated thus</u> :

Put x = 1.7 in the equation :

  • y(1.7) = - 16(1.7)² + 36(1.7) + 4
  • y = 18.89 feets

Therefore, the height of the baseball after 1.7 seconds will be 18.89 feets.

Find the vertex and axis of symmetry for f(x)=2x^2-1
vfiekz [6]
<h3>Axis of symmetry is 0 and vertex is (0, -1)</h3>

<em><u>Solution:</u></em>

<em><u>Given is:</u></em>

f(x) = 2x^2 - 1

We have to find the vertex and axis of symmetry

<em><u>The general equation is given as:</u></em>

f(x) = ax^2 + bx + c

Comparing with given equation,

a = 2

b = 0

c = -1

<em><u>The axis of symmetry is given as:</u></em>

x = \frac{-b}{2a}

x = \frac{0}{2(2)}\\\\x = 0

Thus axis of symmetry is 0

The x coordinate of the vertex is the same

x coordinate of the vertex = 0

h = 0

The y coordinate of the vertex is:

k = f(h)

k = f(0)

f(0) = 2(0) - 1\\\\f(0) = 0 - 1\\\\f(0) = -1

Thus, y coordinate of the vertex is -1

Therefore, vertex is (0, -1)
