A watch costs $30. The equation y=30x describes the cost y of x number of watches. Identify the graph of this direct variation.

Choose a second initial value that is 0.01 greater than the initial value from question 9. iterate it using the function, f, ten times. if necessary, you can round your results to the nearest ten-thousandth.

If f(x)=3x+1 and f^-1=x-1/3, then f^-1(7)=
