Graphing an exponential equation with a horizontal transformations

The video tutorial explains how to graph equations by initially ignoring constants and focusing on the basic form. It covers the importance of the Y intercept and how transformations affect the graph, including shifts and changes to the horizontal asymptote. The tutorial provides techniques for graphing and understanding the general shape of the graph after applying transformations.

What is the first step in graphing an equation like y = 2 * 2^X?

• Consider the constants first

• Find the Y-intercept

• Apply transformations immediately

• Graph the base equation

How does adding a constant to the X variable affect the graph?

• Shifts the graph vertically

• Stretches the graph

• Reflects the graph

• Shifts the graph horizontally

If a graph is shifted 4 units to the left, what transformation is applied?

• y = f(x) + 4

• y = f(x - 4)

• y = f(x + 4)

• y = f(x) - 4

What happens to the horizontal asymptote when the graph is shifted up?

• It remains unchanged

• It disappears

• It shifts down

• It shifts up

What is the new horizontal asymptote if the graph is shifted up by 1 unit?

• y = -1

• y = 1

• y = 2

• y = 0
