1. 3*0+5=5
3*3+5=14
3*9+5=32
2. 4-4=0
8-4=4
11-4=7
3. 2-2=0
3-2=1
8-2=6
max is at vertex
in form 
the x value of the vertex is 
given, 
a=6, b=0
the x value of the vertex is -0/(2*6)=0
the y value is 
so vertex is at (0,-1)
since the value of a is positive, the parabola opens up and the vertex is a minimum value of the function
therefore that value is the smallest value the function can be
domain=numbesr you can use for x
range=numbesr you get out of inputting the domain
domain=all real numbers
range is {y | y≥-1} since y=-1 is the minimum

x
cos 54° = x/(320 ft)
x = 320 ft × cos 54°
x = 188 ft
Answer: 188 ft
