functions & graphs

Question 1

possible questions

Answer 1

• inverse function
• domain and range
• transformation of graphs
• exponential graphs
• log graphs
• composite functions

Question 2

inverse function

Answer 2

-flip x and y
-rearrange to y
-f⁻¹(x)

Question 3

transformation of graphs

Answer 3

f(x)+2 = y+2

f(x-2) = x+2

4f(x) = y x 4

f(2x) = x÷2

f(1/2x) = x÷1/2
