Consider the function and its inverse. f(x) = x2 + 4 and f(x) = -x - 4
When comparing the functions using the equations, which conclusion can be made?
The domain of f(x) is restricted to x = 0, and the domain off?(x) is restricted to xz0.
O The domain of f(x) is restricted to xz 0, and the domain off+(x) is restricted to xs 0.
O The domain of f(x) is restricted to xs 0, and the domain of f'(x) is restricted to x2 4.
O The domain of f(x) is restricted to x s 0, and the domain off-+(x) is restricted to x s 4.

Use a calculator to verify that σ(x) = 62, σ(x2) = 1034, σ(y) = 644, σ(y2) = 93,438, and σ(x y) = 9,622. compute r. (enter a number. round your answer to three decimal places.) as x increases from 3 to 22 months, does the value of r imply that y should tend to increase or decrease? explain your answer. given our value of r, y should tend to increase as x increases. given our value of r, we can not draw any conclusions for the behavior of y as x increases. given our value of r, y should tend to remain constant as x increases. given our value of r, y should tend to decrease as x increases.
