A) Write a rule for a polynomial with left end up and right end up behavior, and has a y-
intercept of (0,3)

Me because some of question i don’t understand

An equation where variables are used to represent known values—function notation true or false

The magnitude, m, of an earthquake is defined to be m=log l/s, where i is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and s is the intensity of a “standard” earthquake, which is barely detectable. what is the magnitude of an earthquake that is 1,000 times more intense than a standard earthquake? use a calculator. round your answer to the nearest tenth.
