4. 3-4 Inverses LESSON ESSENTIAL QUESTION
Determine inverses of relations and functions
Graph functions and their inverses
LESSON ESSENTIAL QUESTION
How do we determine and graph inverse relations and functions?
Inverse function
Horizontal line test
Inverse process

5. Graph y = x2 – 2 by making a table of values -2 < x < 2
Now create a new table by switching every x and y value.
Is this considered a function? What is it’s equation?

6. Two relations are considered inverses if one contains (a,b) and the other contains (b,a).

7. Find the inverse of and graph both.

8. INVERSE FUNCTION TEST
Determine if y=2x+1 and y = ½x - 1 are inverses.

9. Given y = 2x + 4, find its inverse.
Graph the function and it’s inverse.

10. Given f(x) = (x+3)2 - 5
Determine if the inverse is a function from the graph.
Find f-1(x)
Graph both and check symmetry
