Answer for Question I need help with piecewise functions. How to find the domain and range and how to write it notation.. is given below:
y=x-5 , x>6you want find the value of y when x=4.5
Firstly find which domain/section this x belongs to,
clearly it belongs to the second domain. then replace the x in the second equation with 4.5, find y’s value.
One thing you should know about piecewise functions is that for each x there will be only one corresponding y, vice versa..
Q.) I need help with piecewise functions. How to find the domain and range and how to write it notation.
Correct Answer isHere is an example.
/ y=3x+2, x<2
| y=4x+7, y=x-5 , x>6you want find the value of y when x=4.5
Firstly find which domain/section this x belongs to,
clearly it belongs to the second domain. then replace the x in the second equation with 4.5, find y’s value.
One thing you should know about piecewise functions is that for each x there will be only one corresponding y, vice versa.
Conclusion:
This correct answer to this statement is Here is an example. / y=3x+2, x<2 | y=4x+7, y=x-5 , x>6you want find the value of y when x=4.5
