Y=f(x)
which passes through points:
(-1,3) and (0,2) and (1,0) and (2,1) and (3,5)
second function is defined: g(x)=2f(x-1)

Calculate g(0)
Calculate g(1)
Calculate g(2)
Calculate g(3)

Hello, and welcome to MHB! We are given:

$$\displaystyle g(x)=2f(x-1)$$

We are also given 5 points in the form:

$$\displaystyle (x,f(x))$$

And so:

$$\displaystyle g(0)=2f(0-1)=2f(-1)=2\cdot3=6$$

Does that make sense? Can you continue?

Just figured it out. Thank you Mark
