Guys, can I have some help?

Which graph shows a function with a range of all real numbers greater than or equal to -1

Xto the second power plus 14x plus 48. what are the factors? we are doing factoring trinomials with a=1

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.
