Question

Desmond: 4.5 Key features of square root functions:

Does a, h, and k act the same in the square root
function as they did in the quadratic function and/or
cubic functions from the last unit? Explain.

Answer 1

No, a, h, and k behave differently in the square root function than they did in the quadratic function and/or cubic functions from the previous course. There is no variable (a) in front of the square root word in the square root function, and the shifts of the function are represented by h and k, respectively. Unlike in quadratic or cubic functions, where h stands for the vertex's horizontal shift and k for its vertical shift. The square root function's scope and range also vary from those of cubic and quadratic functions.
