Answer:
11 inches
Step-by-step explanation:
Take the square root and add 3.
(x -3)² = 64
x -3 = √64 = 8
x = 8 +3 = 11
The original photo was 11 inches on a side.

Answer:
1 - Copy and complete this table for y = 2x
x = -3 | y = -6
x = -2 | y = -4
x = -1 | y = -2
x = 0 | y = 0
x = 1 | y = 2
x = 2 | y = 4
x = 3 | y = 6
2 - Copy and complete this table for y = 2x - 3
x = -2 | y = -7
x = -1 | y = -5
x = 0 | y = -3
x = 1 | y = -1
x = 2 | y = 1
x = 3 | y = 3
x = 4 | y = 5
x = 5 | y = 7
30 is the lowest common multiple
absolute value graph looks like a V, with the vertex at the origin.
1. the domain (x-values) is: (∞, ∞) TRUE
2. the range (y-values) starts at the vertex: [0, ∞) FALSE
3. the function decreases when left of vertex and increases when right of vertex: decreases (-∞, 0) TRUE
4. f(x) = |x| = +/-x
f(-x) = |-x| = +/-x
f(x) = f(-x) so the function is even TRUE
5. every x-value has a corresponding y-value (there are no gaps) so the function is continuous. TRUE
