How do you graph, find the zeros, intercepts, domain and range of #f(x)=abs(x)+4#?
1 Answer
The y-intercept is
The domain is all real numbers and the range is
Explanation:
How to Graph:
Luckily, this is a (somewhat) linear graph. Firstly, we should identify the
If you want a easier explanation, it's basically all x-values become positive. If you plug in 1 for x, it will equal 5 because 1+4=5. If you plug in -1, it will equal 5 again since the -1 becomes 1 due to the absolute value rule.
This becomes somewhat of an equation that looks like this
Zeroes:
As for the zeroes, there are none. This is because it's impossible for
For the y-intercept, plug in 0 for x then add four then you'll get y=4.
Domain/Range:
The domain is all real numbers, because any number can be plugged in without getting a "error" or "undefined" answer. (An example of undefined is plugging in 0 for a denominator in a fraction.)
The range is
