Question 316454: 1. y = 2sqrt(x + 3) by graphing 5 points. Use the endpoint of the function as your first point.
y = 2 sqrt (x) + 3
x = 0, y = 2sqrt(0) + 3 = 3
x = 1, y = 2sqrt(1) + 3 = 5
x = 9, y = 2sqrt(9) + 3 = 9
x = 16, y = 2sqrt(16) + 3 = 11
x = 25, y = 2sqrt(25) + 3 = 13
How do I find out what the endpoint is exactly ?

Question 316390: If the average radius of the orbit of Venus is 0.723 AU, then how many years does it tale for Venus to complete one orbit of the sun? Use the following information to solve.
According to Kepler's third law of planetary motion, the ratio T^2 over R^3 has the same value for every planet in our solar system. R is the average radius of the orbit of the planet measured in astronomical units (AU), and T is the number of years it takes for one compete orbit of the sun. Jupiter orbits the sun in 11.86 years with an average radius of 5.2 AU, whereas Saturn orbits the sun in 29.46 years.
