Problem 3 Got It? Reasoning: Does -f(x) have the same zeros? Explain.
Yes; -f(x) is f(x) reflected across the x-axis, so the zeros will stay the same.
Yes; -f(x) is f(x) reflected across the y-axis, so the zeros will stay the same.
No; -f(x) is f(x) reflected across the x-axis, so the zeros will not stay the same.
No; -f(x) is f(x) reflected across the y-axis, so the zeros will not stay the same.    6

Problem 4 Got It? Wind-Generated Power: The power P (in kilowatts) generated by a wind turbine varies directly as the cube of the wind speed v (in meters per second). A wind turbine generates 210 kW of power in a 12 mi/h wind. How much does this turbine generate in a 20 mi/h wind?
