Answer:
Explanation:
For any function f(x), you will substitute the value of x into the given function. For instance, f(x) = 2x+3. The value substituted in was the original variable, x. However, if x=2, then f(2) = 2(2)+3 = 4+3 = 7. This still applies even if the given x is another function, such as x+2. So for the given function f(x) = 4x-11, f(x+2) = 4(x+2)-11. This simplifies to 4x+8-11, which simplifies to 4x-3.
