we know that
The formula of law of cosines is equal to
where
a, b and c are sides. C is the angle opposite side c
In this problem we have
substitute the given values
Graph f(x)=2^x+1 and g(x)=-x+4 on the same coordinate plane what is the solution to the equation f(x)=g(x)
1 answer:
Answer:
x = 1
Step-by-step explanation:
The graph shows the curves cross at x=1.
The solution is x = 1.

<em>Additional comment</em>
I personally find it more convenient to look for the zeros (x-intercepts) of the difference f(x)-g(x). That way, I'm only graphing one function, and I don't have to look all over the graph to try to find the point of intersection. (The solution is always on the x-axis.) The attached graph shows f(x) - g(x) as a dashed green line.
