If f(x)=27 and x=9, what is the constant of variation of (k) for this function?

hint: use f(x)=kx and solve for k.

give your answer as a number.

Lesson 9-3 for items 8-10, a square is drawn in the coordinate plane, with vertices as shown in the diagram. then the square is reflected across the x-axis. -2 4 8. the function that describes the reflection is (x, y) - a. (x, y-3). b. (x, y-6). c. (-x, y). d. (x,- y).
