Question

Graph f(x)=2x−1 and g(x)=−x+5 on the same coordinate plane. What is the solution to the equation f(x)=g(x)f(x)=g(x) ? Enter your answer in the box.

Answer 1

using a graphical tool
 the solution is (2,3) see the attached figure

proceed to check it

f(x)=2x−1
g(x)=−x+5

f(x)=g(x)
2x-1=-x+5
2x+x=5+1------------ >3x=6-----------> x=2
y=2x-1=2*2-1=3

the solution is the point (2,3)  (see the graph in the attached figure)
