Question

Graph f(x)=2x+1 and g(x)=−x+7 on the same coordinate plane.
What is the solution to the equation f(x)=g(x) ?
Enter your answer in the box.
x =

Answer 1

For this case what you must do is to graph both lines. (See attached graph) and see where both are cut.
 We note that both lines are cut at the point (2,5)
 Therefore the solution for f (x) = g (x) is x = 2
 answer
 x = 2
