Graph Analysis and Function Concepts

The video tutorial covers analyzing graphs of functions, focusing on domain, range, and evaluating functions from graphs. It explains the vertical line test, finding zeros, and describes graph behavior in terms of increasing and decreasing intervals. The tutorial also covers calculating the average rate of change, identifying even and odd functions, and introduces parent and step functions. Finally, it discusses piecewise functions and how to graph them.

What is the main focus of the video tutorial?

• Analyzing graphs of functions

• Solving algebraic equations

• Learning about geometry

Which of the following is NOT a parent function discussed in the video?

• Exponential function

• Cubic function

• Quadratic function

How is the domain of a function represented when using interval notation?

• Using arrows

• Using inequalities

• Using a number line

• Using brackets and parentheses

What does a bracket indicate in interval notation?

• The point is not included

• The interval is infinite

• The interval is undefined

• The point is included

What is the range of a function if it includes all values from -3 to 3?

• (-3, 3)

• [-3, 3]

• (-3, 3]

• [3, -3]

What does the vertical line test determine?

• If a graph is symmetrical

• If a graph is quadratic

• If a graph is linear

• If a graph is a function

What happens if a vertical line crosses a graph more than once?

• The graph is a function

• The graph is quadratic

• The graph is not a function

• The graph is linear

What is the x-intercept of a function?

• The point where y is zero

• The point where the graph is horizontal

• The point where the graph is vertical

• The point where x is zero

How do you find the zeros of a function?

• Set the graph to zero

• Set the denominator to zero

• Set the numerator to zero

• Set the function to zero

What does it mean if a graph is increasing?

• The graph is undefined

• The graph remains constant

• The graph moves upwards

• The graph moves downwards
