Answer:
A
Step-by-step explanation:
The domain of a function is the span of x-values covered by the graph.
From the graph, we can see that it stretches from x=-7 to x=2.
However, note that at x=-7, the dot is closed (shaded in). In other words, x=-7 <em>is</em> in our domain.
On the other hand, at x=2, the dot is not shaded. So, x=2 is <em>not</em> included in our domain.
Therefore, our domain all are numbers between -7 and 2 including -7 (and not including 2).
As a compound inequality, this is:
So, our answer is A.
Also note that we use x instead of p(x) because the domain relates to the x-variable. If we were to instead find the range, then we would use p(x).
Answer:
So Equation ( 1 ) is NOT Equivalent to Equation ( 2 )
Step-by-step explanation:
Given:
..............Equation ( 1 )
................Equation ( 2 )
To Find:
Whether Equation ( 1 ) is Equivalent to Equation ( 2 )
Support your answer by evaluating the expression for t = 2.
Solution:
For t=2 Equation ( 1 ) we get
For t=2 Equation ( 2 ) we get
From above we get two different values
So Equation ( 1 ) is NOT Equivalent to Equation ( 2 )
