Determine a point on f-1(x). Points on f(x) (5,4), (2,1), (0,4), (3,4), and (7,7). A. (5,4) B. (0,4) C. (7,7) D. (4,4)

9514 1404 393

  C.  (7, 7)

Step-by-step explanation:

Points on the inverse relation are found by reversing the coordinates of points on the function. Then the inverse relation has points ...

  (4, 5), (1, 2), (4, 0), (4, 3), (7, 7)

Of these, only (7, 7) is listed as a choice.

We note that the inverse relation is NOT a function, as it has multiple instances of (4, _).

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
