Question

Describe the transformation from the parent function of f ( x ) = x 2 to g ( x ) = 6 x 2.(Need answer in less than 2 hours!)

Answer 1

Answer: (b) vertical stretch by a factor of 6

Explanation:

Consider h(x) = A(x - h)² + k

• A is the vertical stretch by a factor of A
• h is the horizontal shift (positive = right, negative = left)
• k is the vertical shift (positive = up, negative = down)

f(x) = x²

g(x) = 6x²
