Directions: Using the integers -9 to 9, at most one time each, fill in the boxes to create a square root function, its domain, and the greatest possible x-intercept.
Hint
How do each of the values you can choose affect the values of the domain and x-intercept?
Answer
The greatest possible x-intercept is 9, from the following choices:
y = 1√(x + -8) + -1
domain: x ≥ 8
x-intercept: 9
