Our new unit is about exponential and logarithmic functions. This formative will help you to review some basic function information from earlier in the year.
Question 1
1.
Which of the following relations are functions?
Question 2
2.
Sketch a relation that is not a function on the coordinate plane below.
Question 3
3.
Explain how you know the relation you graphed is not a function.
Question 4
4.
State the domain of the function shown. Each line is 1 on the graph.
Question 5
5.
State the range of the relation shown. Each line is 1 on the graph.
Question 6
6.
Evaluate the function below for x = -7:
Question 7
7.
Given g(x) below, find g(n + 2).
Question 8
8.
Given f(x) and g(x) below, find f(g(3)). Remember, this is function composition, where the output of one function becomes the input for the other.
Question 9
9.
Given f(x) and g(x) below, find f(g(x)) in a simplified form.
Question 10
10.
Given f(x) and g(x) below, find g(f(x)) in a simplified form.
Question 11
11.
Your answers to #9 and #10 should not be the same. Explain why.
