Understanding Transformations and Functions

Mr. Wynn's Algebra 2 DCA review covers prediction equations, transformations, graphing, determinants, and inequalities. The video guides students through using calculators for prediction equations, understanding transformations, and solving mathematical problems. It emphasizes the importance of correct mathematical vocabulary and provides step-by-step instructions for solving complex equations.

What is the first step in finding a prediction equation using a calculator?

• Turn off the calculator.

• Press the 'graph' button.

• Enter data into the calculator's memory.

• Press 'stat' and then 'edit'.

When entering data into the calculator, what should the first row represent?

• Y-values

• X-values

• Graph titles

• Equations

How do you handle an incomplete data point when entering data into the calculator?

• Skip it.

• Delete all data.

• Enter zero.

• Enter a placeholder value.

What is the purpose of rounding to three decimal places in prediction equations?

• To ensure accuracy.

• To make the equation look neat.

• To match the calculator's display.

• To simplify calculations.

What does a negative sign in a transformation equation indicate?

• A reflection over the x-axis.

• A vertical stretch.

• A horizontal shift.

• A vertical compression.

What does a factor greater than one indicate in a transformation?

• Reflection

• Vertical compression

• Horizontal shift

• Vertical stretch

In graph transformations, what does the 'H' in the formula represent?

• Stretch factor

• Vertical shift

• Horizontal shift

• Reflection

What is the formula for finding the determinant of a 2x2 matrix?

• a + b - c + d

• a * d - b * c

• a * b + c * d

• a - b + c - d

What does the 'R' in the number line formula represent?

• The average

• The slope

• The range

• The center

How do you determine which piece of a piecewise function to use?

• By the value of the function

• By the slope of the line

• By the graph's appearance

• By the condition of the variable
