Answer:

Step-by-step explanation:

Whenever you're given something other than just 'x' as the input into the function, all you need to do is plug that expression into x in the original function and simplify

[tex]f(x) = 2x^2 - 5x[/tex]

[tex]f(x-2) = 2(x-2)^2 - 5(x-2)\\f(x-2) = 2(x^2-4x+4) - 5x + 10\\f(x-2) = 2x^2 - 8x+8-5x+10\\f(x-2) = 2x^2-13x+18[/tex]
