Range of a function calculator
|
 1. `y=1/(x+4)-5`
2. `y=(x+4)/(x-3)`
3. `(-2,1),(-1,3),(2,1),(3,2)`
|
Example (with steps)1. `y=(-2,1),(-1,3),(2,1),(3,2)`, find Range of a function
Solution:
domain`={-2,-1,2,3}`
range`={1,3,2}`
2. `y=(1,10),(2,10),(3,10)`, find Range of a function
Solution:
domain`={1,2,3}`
range`={10}`
