Graphs are used to show relationships between related entities. See attachment for the graph that shows the relationship between the number of students and the number of buses.
Given that:
The given parameters can be represented as:
Where:
people
bus
When there is nobody (i.e. 0 people), then the number of bus will also be 0. So, we have:
To sketch the graph that represents the given relationship, we simply plot points (0,0) and (45,1) and connect both points
See attachment for the graph

The graph of the parent function is horizontally compressed by a factor of 2 and reflected over the y-axis ⇒ Last answer
Step-by-step explanation:
Let us revise some transformation
A horizontal compression (or shrinking) is the squeezing of the graph toward the y-axis.
A horizontal stretching is the stretching of the graph away from the y-axis
- If k > 1, the graph of y = f(k•x) is the graph of f(x) horizontally shrunk (or compressed) by dividing each of its x-coordinates by k.
- If 0 < k < 1 (a fraction), the graph of y = f(k•x) is the graph of f(x) horizontally stretched by dividing each of its x-coordinates by k
- If k should be negative, the horizontal stretch or shrink is followed by a reflection across the y-axis
∵ y = √x is a parent function
∵ Its graph transformed to produce the graph of y = √(-2x)
- That means x is multiplied by a factor k, then it is compressed
or stretched horizontally
∵ k = -2
- The factor is -2, where 2 is greater than 1, then it is compressed
horizontally as the first rule above and the negative means
reflected across the y-axis as the third rule above
∴ The graph of the parent function is compressed horizontally and
reflected across the y-axis
The graph of the parent function is horizontally compressed by a factor of 2 and reflected over the y-axis
