Question

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

Answer 1

Answer: Square root of x+3

Explanation:

Insert the denominator to 3

Answer 2

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

EXPLANATION

The given rational function is

`y = √(x - 1) + 4`

The base of this function is

`y = √(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.
