One-to-One Functions. ... If no horizontal line intersects the graph of the function f in more than one point, then the function is 1 -to- 1 . A function f has an inverse f−1 (read f inverse) if and only if the function is 1 -to- 1 .
Answer:
Step-by-step explanation:
- 4x - 5 = - 3*(2x + 10)
- 4x - 5 = - 6x - 30
- 4x + 6x = 5 - 30
- 10x = - 25
- x = - 2.5
Option A: y = 1/4x is the right answer
Step-by-step explanation:
The proportional relationship is defined as the increase/decrease in one quantity causes increase/decrease in other quantity.
The general form is:
y = kx
The proportional equations usually do not have any term that is added or subtracted.
comparing the given options with general form we can see that only one option is relatable to the general form of proportion.
Hence,
