That's a quadratic equation in
, which means we get an extra square root and
at the end.
We factor,
Answer:
The answer is "It has the same domain as the function f(x) = --x".
Step-by-step explanation:
If we consider its parent function that is: y= x
Domain function is: 
The range function is: 
The function has both the same (domain and range).
What’s the rest of your question???
You will have to divide the beef Maria bought by the amount of beef she uses to make the tacos. She can make 15 tacos.
As you see in the picture, there are two lines that could maybe represent two linear functions. However, this is not true because of the solid point and the hollow point. This is an inequality equation that has points of discontinuity.
Points of discontinuity are breaks in the graph that are a result of an undefined point when the f(x) is substituted with a point of x that is not part of the solution. So, technically, the graph is made from one rational expression.
So, when it says f(-2), this is the y-value at x=-2. That means f(-2)=2, f(0)=3 and f(4)=-1. Specifically, there are two points at x=0, but we take the solid point only.
