The video tutorial explains how replacing f(x) with f(x) - 5 affects the graph of the function. It begins by plotting the original function f(x) = 5 * 2^x and then demonstrates how the graph shifts to the right when transformed to f(x) - 5. The tutorial uses visual aids to show the shift and explains the concept of horizontal translation in function graphs.

What is the initial function given in the problem?

• f(x) = 2^x + 5

• f(x) = 5 * 2^x

• f(x) = 2 * 5^x

• f(x) = 5 + 2^x

Which line represents the original function f(x) = 5 * 2^x?

• Black line

• Yellow line

• Blue line

• Red line

What does subtracting a constant from x in a function do to its graph?

• Shifts the graph up

• Shifts the graph down

• Shifts the graph to the left

• Shifts the graph to the right

Which line represents the graph of f(x - 5)?

• Yellow line

• Red line

• Blue line

• Green line

If f(0) = 5 for the original function, what is f(0) for the function f(x - 5)?

• 10

• 5

• 0

• -5

What is the effect of replacing x with x - 5 in the function f(x)?

• The graph shifts 5 units up

• The graph shifts 5 units to the right

• The graph shifts 5 units down

• The graph shifts 5 units to the left

In the context of graph transformations, what does a negative sign before a constant indicate?

• A shift downwards

• A shift upwards

• A shift to the right

• A shift to the left

How does the point (0, 5) on the original graph change in the graph of f(x - 5)?

• It becomes (5, 0)

• It becomes (0, -5)

• It becomes (-5, 0)

• It becomes (5, -5)
