How to do a vertical stretch

The video tutorial explains how to apply a vertical stretch to a mathematical equation. It begins with setting up the problem and introduces the formula Y = a * F(X). The instructor then demonstrates how to apply a vertical stretch by a factor of 3, showing the step-by-step process of multiplying the equation by the factor. The tutorial concludes with the final equation after the transformation.

What is the initial function setup mentioned in the video?

• X - 1/3

• 3X - 2

• X + 2

• 1/3 X - 2

What does the 'a' represent in the formula Y = a * F(X)?

• The vertical stretch factor

• The horizontal shift

• The y-intercept

• The slope of the line

How do you apply the vertical stretch factor to the function?

• Add the factor to the function

• Multiply the factor with the entire function

• Subtract the factor from the function

• Divide the function by the factor

What is the result of multiplying 3 by the term -2 in the function?

• -6

• 6

• -3

• 3

What is the new equation after applying the vertical stretch?

• Y = 3X + 2

• Y = X + 6

• Y = 3X - 2

• Y = X - 6
