Answer:

Step-by-step explanation:
For this case we have the following functions:

The first thing we must do for this case is to subtract both functions.
We have then:

Substituting we have:

Rewriting we have:

Evaluating the obtained function for x = 3 we have:

Answer:
The value of the function evaluated at x = 3 is:

Answer:
i think the answer is ( C )
Answer:
<u>System of equations</u>


--- solution

Step-by-step explanation:
Solving (a): Linear equations with 1 solution
The only condition to this is that, the system must have 1 solution.
Other than that, there is no other condition.
A linear equation is represented as:

For the equation to have 1 solution;

And example of such equation is:


Solving (b): The graph
See attachment for graph
The solution is the point of intersection of both lines of the graph. So, we have:

Ans A
<span>look at the graph for x = 2.... </span>
<span>2^4 = 16 ..and the graph looks like it approx = 8 for x=2 </span>
<span>this suggests (1/2)x^4 </span>
<span>you can eliminate answers C and D straight off because the graph is never negative</span>
