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)

Hello.
Simply plug -1 into 2x+2.
f(x) = 2x +2
f(-1) = 2 (-1) +2
f (-1)= -2+2
f(-1) = 0
Hope this helped.

Answer:
Subtraction property of equality
Step-by-step explanation:
Given the equation;
2x + (x+5) = 41
open the parenthesis;
2x+x + 5 = 41 (Associative property)
3x+5 = 41
Subtract 5 from both sides
3x + 5 = 41
3x + 5- 5 = 41 - 5 (Subtraction property of equality)
3x = 36
Divide both sides by 3;
3x/3 = 36/3
x = 12 (Division property of equality)
Hence the required property is Subtraction property of equality
