It is convenient to follow directions. Create a chart with activities as column headings. Since the data is divided according to gender, you would put gender on the row headings. Fill in the given numbers (black), and make the totals come out (blue).
The numbers in the row total column are exactly that: the total of the numbers in the row. (A spreadsheet can do the actual addition or subtraction for you.)
The y-intercept of a function is the point where the graph crosses the
- The factors of the Jared's graph are: (x - 10), (x + 3) and (x + 9)
- The y-intercept is -13.5
- The standard equation of the function is:
<u>(a) The factors</u>
First, we write out the points where the function cross the x-axis.
The points are:
Equate the above points to 0
Hence, the factors are: (x - 10), (x + 3) and (x + 9)
<u>(b) The y-intercept</u>
This is the point where the graph crosses the y-axis.
From the attached graph, the graph crosses the y-axis at -13.5.
Hence, the y-intercept is -13.5
<u>(c) The standard form</u>
In (a), we have:
Multiply the above equations
Expand
Expand
Collect like terms
Replace 0 with y
Hence, the standard form is:
