Question

Describe the graph of the function. y =Square root of x-1 + 4

Answer 1

ANSWER

The graph of the function starts from (1,4) and moves up right.

EXPLANATION

The given rational function is

$y = \sqrt{x - 1} + 4$

The base of this function is

$y = \sqrt{x}$

The -1 under radical sign means the graph of the base function is shifted 1 unit right.

The +4 shows that base function is shifted up by 4 units.

The graph of the function therefore starts from (1,4) and moves up right.
