Practice Questions on Functions
Functions are fundamental to all that follows, and for that reason it's a good idea for you to test your knowledge by answering a few questions. You should be able to get all of these correct.
If f(x)=2x+2 what is f(2)?
One of the most important applications of functions is as mathematical models.
What are the units of the output of the model of the height of the missile?
What are the units of the input of the model of the length of the day
If what is f(1)?
If f(x)=x^2 and g(x)=2x, what is g(f(2))
?
If f(x)=x^2 and g(x)=2x, what is f(g(2))?
How'd you do? It's ok if you made dumb mistakes, but if you really don't understand, you should go back and review this chapter again before moving on.
