Question 362242: what is the range of the function f(x)=2x+7
Answer by nyc_function(2741)   (Show Source):
You can put this solution on YOUR website! The range of a function is the complete set of all possible resulting values of the dependent variable of a function, after we have substituted the values in the domain.
In plain English, the definition means:
The range of a function is the possible y values of a function that result when we substitute all the possible x-values into the function.
When finding the range, remember:
•Substitute different x-values into the expression for y to see what is happening
•Make sure you look for minimum and maximum values of y
•Draw a sketch!
Can you do it now?
