Mr. Patel decided to challenge his Algebra I students by asking them to describe the effect 2f would have on the function f(x) = x2. Use your understanding of horizontal and vertical stretches to explain the result.
The parabola would stretch both vertically and horizontally by a factor of 2.
The parabola would stretch vertically by a factor of 2 and shrink horizontally by a factor of 2.
The parabola would shrink vertically by a factor of 2 and stretch horizontally by a factor of 2.
