Learning how to identify reflections of multiple functions

The teacher addresses a student's question, emphasizing the importance of understanding the order of operations and the role of parentheses in mathematical expressions. The discussion includes the concept of negatives inside functions and their impact on reflections across axes. The teacher clarifies common misconceptions and stresses the need to understand the function's structure to determine what is inside or outside the function.

What is the correct order of operations when using a calculator for the expression -3X^2?

• Subtract first, then square

• Multiply first, then square

• Add first, then multiply

• Square first, then multiply

Why is a negative sign not typically placed inside a function in Algebra 2?

• Because it reflects the function across the X-axis

• Because it makes the function undefined

• Because it changes the function's domain

• Because it reflects the function across the Y-axis

What happens when a negative sign is outside of a function?

• It reflects the graph across the Y-axis

• It reflects the graph across the X-axis

• It shifts the graph downwards

• It shifts the graph upwards

When is a value considered to be inside a function?

• When it is under a radical

• When it is outside the parentheses

• When it is added to the function

• When it is multiplied by the function

What is the function of the square root of X?

• It is a linear function

• It is a quadratic function

• It is a radical function

• It is an exponential function
