Find the values of the variables, giving brief reasons for your answers.

Find the zero function by factoring (try to show work) h(x)=-x^2-6x-9

Describe the domain and range of y=2(3)^x-2+5

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 =
