they are both parabolas.
#1 opens up, so its range has a minimum
#2 opens down, so its range has a maximum
So, just find the vertex; that defines the closed end of the range.
The following functions are defined for all real values of x. Find the range of the funcion.
1) y=m^2-4m-5
2) y=-9v^2-18v-55.
Thank you for your help. (Please step by step.
