Which function has a translation of 2 units right and a vertical stretch by a factor of 5?

• f(x)= 5(x - 2)²

• f(x) = 5(x + 2)²

• f(x) = (x - 2)² - 5

• f(x) = (x + 2)² + 5

How does y=.35x² compare to y=x²?

• They are the same graph. 

• y=.35x² is wider than y=x².

• y=.35x² is more narrow than y=x².

• y=.35x² is moved down from y=x².

Transformation: 
Which equation would represent a parabola that is WIDER than the parent function, f(x) = x²? 

• g(x) = x² + 4

• g(x) = 4x² 

• g(x) = x² - 4 

• g(x) = ¹/₄x²
