Step-by-step explanation:
Putting both functions into a graphing calculator, we can easily find the domain and range. (attatched)
By looking at the graph, we can tell that f(x) is a quadratic function because of the symmetry. We can also tell that it never goes below 4. Knowing this, we can determine the domain and range.
Domain: {x | all real numbers}
Range: {y | y > 4}
By looking at the graph, we can tell that g(x) is an exponential function because it has a curve, and never goes below the x. Knowing this, we can determine the domain and range.
Domain: {x | all real numbers}
Range: {y | y > 0}
Answer:

Step-by-step explanation:
Given
and 
Required
Which compares them correctly

This is incorrect because 0.63 is greater

This is also incorrect because 0.63 is greater

This is also correct because 0.63 is greater

This is also incorrect because 0.63 is greater
The average speed = (speed 1 + speed 2)/2
the average speed = (80/10 + 100/20)/2
the average speed = (8 + 5)/2
the average speed = 13/2
the average speed = 6.5 km/minute
Turn the text into an eqation:
48-x = 4x-7
5x = 55
x = 11
