Answer:

Step-by-step explanation:
We want to write a quadratic function in vertex form whose vertex is (1, 0) and passes through the point (2, -17).
Recall that vertex form is given by:

Where (<em>h</em>, <em>k</em>) is the vertex and <em>a</em> is the leading coefficient.
Since our vertex is at (1, 0), <em>h</em> = 1 and <em>k</em> = 0:

It passes through the point (2, -17). Hence, when <em>x</em> = 2, <em>y</em> = -17:

Solve for <em>a: </em>

In conclusion, our quadratic function in vertex form is:

Answer:
For question #2 about Teresa, it would cost her $1,004.80 to fence all around the circle garden.
Step-by-step explanation:
C = 2πr
C = 2 x 3.14 x 8
C = 50.24 ft.
50.24 x $20 = $1,004.80

Step-by-step explanation:
Given
In 1990; Income= $39000
In 2010; Income= $70768
Solving (a): An equation in form of f(x) = ax + b
First, we need to determine the slope, a

Taking y as income and x as year index.
When x = 0; y = 39000
When x = 20; y = 70768
Substitute these values in the above formula



Next, is to determine the formula using:

<em>Considering :When x = 0; y = 39000, we have</em>
<em />
<em />
<em />
<em />
<em>Make y the subject of formula</em>
<em />
<em />
<em />
<em>Express y as a function of x</em>
<em />
<em />
Solving (b): Income in 2005
<em>In 2005, x = 15</em>
So:
becomes
