1. Determine the equation of a graph of f(x) = x^2 that has been transformed so that it now has a vertex of (4,-1) opens down, and was stretched so that it passes through the point (5,-3).
2. The domain of y=5f(2x+4)+3 where f(x) = 1/x is?
3. If the terminal arm of angle θ intersects the unit circle at the point (-3/8, - √55/8), then, to the nearest hundredth of a radian, θ is?
4. Given the equation 6cosθsinθ - 2cosθ = 0, determine the general solution
5. Find the numerical coefficient of the simplified term involving x^-7 of (x+1/2x)^9. Round to the nearest hundredth?-.
Please and thank you in advance.
