Answer:
Step-by-step explanation:
As the value of a increases, the radical function sweeps out higher, increasing the range of the function. The k value moves it up or down. A "+k" moves up (for example, +3 moves the function up 3 from the origin). The h value moves it side to side. A positive h value moves to the right and a negative h value moves to the left. For example, √x-3 moves 3 to the right and √x+3 moves 3 to the left.
In summary, a and k affect the range of the function, k being the "starting point" and a being the "ending point"; h affects the domain of the function.
