Aheated piece of metal cools according to the function c(x) = (.5)x ? 7, where x is measured in hours. a device is added that aids in cooling according to the function h(x) = ? x ? 2. what will be the temperature of the metal after two hours?

What is the average rate of change for this function for the interval from x=2 to x=4 ?

Which inequality is equivalent to -3x < -12? x < 4 , x < -4 , x > 4, x > -4
