X^2 - 8x = (x - 4)^2 - 16
we add 16 to give x^2 - 8x + 16 which is a perfect square
x^2 - 8x + 16 = (x - 4)^2
answer is 16
Answer:
The correct answer should be 11

Step-by-step explanation:
The given functions are:

and g(x)=-1
To find the x-value of the point of intersection of the two functions, we equate the two functions and solve for x.



The graph that shows the input value for which f(x)=g(x) is the graph which shows the point of intersection of f(x) and g(x) to be at x=-2.
