Which of the following are characteristics of the graph of the square root
parent function? Check all that apply.
A. It has a domain of x 0.
B. It has a range of yz 0.
O c. It starts at the origin.
D. It is a straight line.

Choices A and B have typos in them, so its not clear what you're trying to say for those parts. However, the domain of is meaning that x can be 0 or larger. In other words, we can't have x be negative. Similarly, y is the same story because has the inverse , but only when , so therefore as well. In short you can say both x and y are nonnegative.

To summarize so far, the domain is and the range is

Since x = 0 and y = 0 are the smallest x and y values possible, this means (x,y) = (0,0) is the left-most point or where the graph starts. This is the origin. Choice C is a true statement.

Choice D on the other hand is not a true statement. Graph out and you'll see that a straight line does not form, but instead a nonlinear curve that grows forever. That growth gradually diminishes as x gets larger. Algebraically you can pick three points from the function and show that the slopes are different. Say the three points are P, Q and R. If you can show that slope of PQ does not equal slope of QR, then the function is not linear.

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
