3/ If f(x) = 2x -5 Find f(x-1)=

Explanation: Here we have function f(x) = 2x - 5

and we're asked to find f(x - 1).

Don't be thrown off if you're asked to plus a variable into a function.

If f(x) = 2x - 5, then f(x - 1) = 2(x - 1) - 5.

Remember to use parenthses when substituting into a function.

So simplifying on the right side, we would distribute the 2

through the parenthses and we have 2x -2 - 5.

Now combining like terms, we have 2x - 7
