Explain what a, h, and k do to transform the following equation. Be sure to mention the shift or transformation each variable do es and how if each varible is a positive or negative : y= a|x-h|+k.
2 answers:
Answer:
a: vertical stretch
h: horizontal translation (remember not to get signs mixed up!)
k: vertical translation
Explanation:
A → Whether opens down or up; fractions [vertical shrink], whole numbers [vertical stretch]
- H → OPPOSITE terms of what they really are [phase shift]
K → NORMAL term [vertical shift]

P(bull's-eye) = 700/30000 x 100% = 2.33% ≈ 2% option A is the correct answer.
Y = ax + b; 0.89 = a * 2 + b and 2.09 = a * 5 + b => => 2.09 - 0.89 = a * 5 + a * 2 + b - b => 1.20 = 3 * a => a = 1.20 / 3 => a = 0.40; b = 0.89 - 0.40 * 2 => b = 0.89 - 0.80 => b = 0.09; y = 0.40x + 0.09 => 0.40x - y + 0.09 = 0 is the linear equation.
