Find the area of triangle as a function of
Answer to Problem 67E
The domain of the function is all real values of
Explanation of Solution
Given information:
A right triangle is formed in the first quadrant by the
Calculation:
Consider the given triangle,
A line is passing through the points
Consider base of given right triangle
Area of triangle A is
Now find the function of area in terms of
Now to get
The slope of line is
Slope of line with coordinates
Slope of line with coordinates
Thus,
Hence area is
Now determine the domain of function,
As the triangle is in first quadrant so then
We will include those values in the domain where denominator is non zero.
For
Hence the domain of the function is all real values of
