To graph the function and find Domain, Range.
Answer to Problem 1CR
Domain =
Range =
Explanation of Solution
Given information:
Formula Used: Square root function cannot be negative.
Calculation:
As the domain of square root function is greater than or equal to zero i.e. cannot be negative.
So,
Squaring both sides,
Hence,
Domain =
As,
Now, Add 7 both sides
So,
As,
Range =
To find the transformation, compare the function to the parent function and check to see if there is a horizontal or vertical shift, reflection about the x-axis or y-axis.
Parent function:
Horizontal shift: none
Vertical shift: up 7 units
Stretch or shrink: none.
