PART A (1 in diagram)
Each mapping diagram represents a function because none of the elements in the inputs maps on to two different elements in the outputs.
1. The domain of the given function f(x) is the set {10, 20, 30}.
All we can say about
is that, it has a range of {10, 20, 30}.
This is because the domain of a function becomes the range of its inverse function.
2. If the graph of a function f(x) includes the point (3, 0), then the graph of the inverse function ,
will contain the point (0,3).
Reason:The point on the graph of the inverse function is obtained by reflecting the corresponding point on the graph of the function in the line y=x. We just have to swap the coordinates.
In simple terms the domain of the function becomes the range of the inverse function and vice versa.
3. If the first term in an arithmetic sequence is 2.
Then we have a=2.
If the twelfth term is 211, then
Put a=2 into this equation.
Solve for d.
If
then
Substitute a=2 and d=19
Therefore n=8
Answer:
Step-by-step explanation:
- The equation of the line in point-slope form is:
Where m is the slope and is a point of the line.
- The equation of the line is written is slope-intercept form, where the slope is
.
- By definition, when two lines are perpendicular to each other, the slopes are the negative reciprocals. Therefore, the slope of the perpendicular line must be -3.
- Substitute the point P and the slope -3 into the equation in point-slope form, therefore, you obtain:
