How can you<br> change the equation y = mx + b to<br> shift the graph down?
IrinaK [193]

Step-by-step explanation: To shift the graphs up and down on the coordinate system, you need to manipulate or change the y-intercepts.

The y-intercept is just the constant term in the equation.

As long as the slopes remain the same, the graphs can be

translated up or down by changing the constant value.

Take a look at these lines graphed below.

Notice that y = x + 11 is the same as y = x + 4 but

y = x + 11 is translated 7 units down to get y = x + 4.

Hey there! posted picture of question help please
Amiraneli [1.4K]
For this case we have the following function:
 f (x) = (1/6) ^ x
 We must evaluate the function for x = 3
 We have then:
 f (3) = (1/6) ^ 3
 Rewriting:
 f (3) = (1/216)
 Answer:
 
The function evaluated at x = 3 is:
 
f (3) = (1/216)
