Please use " ^ " to indicate exponentiation. Then: <span>f(x) = (x – 3)^2 – 1.
By comparing this equation to y-k = (x-h)^2
you can see that h=3 and k= -1. Thus, the vertex is at (3, -1).
The axis of symm. goes thru the vertex, so is x = 3.
The domain is the set of all real numbers.
Since the vertex is (3, -1), the smallest value y can take on is -1. Thus, the range is [-1, infinity)

Answer:
x=8 y=4
Step-by-step explanation:
x=12-y
12-y-y=4
-2y=-8
y=4
x=12-y
x=12-4
x=8
Answer:176

Answer:
20.6155281 (round if ya want)
Step-by-step explanation:
Pythagorean Theorem
a^2 + b^2 = c^2
a = 16
b = 7 + 6 (13)
c = x
