Choose the polynomial function whose graph COULD be the one shown here. A)
f(x) = x3 + x2 - 25% - 25
B)
f(x) = x3 + x2 + 25x + 25
C)
f(x) = -x3 + x2 - 25x - 25
D)
f(x) = -x3 + x2 + 25x + 25

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?

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =

If you answer 2+2 you will get over 80 points
