What happens if you use the "2" shown as part of the function input, and the coefficient "2" on the x, and ADD 2*2=4 to the linear expression?

2x-5%2B2%2A2
2x-5%2B4
2x-1

Now, check how this works for some function g(x).
g%28x%29=2x-1
Use input of x-2 for g.
g%28x-2%29=2%28x-2%29-1
g%28x-2%29=2x-4-1
highlight%28g%28x-2%29=2x-5%29
