okay first off: we both use the same virtual school and i just thought that was cool lol
the equation for g(x) is g(x)=4x-5 so when you substitute in x it becomes
g(x)= 4(2) -5 or g(x)= 8-5 which equals g(x)=3
when you substitute in x, f(x) becomes
f(x)= 2 + 1 which equals f(x)=3
therefore when x=2, both functions are equal :)
hope this helps!!
