Which of the following graphs could depict the function f(x)=-m(x-d)^1/5 if m and d were positive?

Only the second option is correct.

Step-by-step explanation:

The first option is a square root function. Therefore this cannot be the graph of .

For the second option the origin lies on the positive x-axis which is what we expect from the graph of , and for the negative value of x, is positive, which is a property of the expression . Therefore this could be the graph of .

In the third option the origin lies on the negative x-axis, and is positive for postive values of x, something that we do not expect from the graph of , therefore this cannot of the right answer.

For the fourth option negative values of x give positive values for , but this graph has its origin at a negative value of x, therefore this cannot be the graph of .

Thus only the second option is correct.

4sqrt5

step-by-step explanation:

the base has dimensions of 8 x 4, so the diagonal is 64 + 16 square rooted or 4sqrt5.

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.
