To evaluate the function f(x) = |x + 1|, when x = -5, we have to substitute all values of x in the function with -5. Doing this, we get:
f(-5) = |-5 + 1|=
=|-4|
Since absolute value is always positive, the answer is 4.
Hello!
To find f(-5), if f(x) = |x + 1|, substitute the value of x, which is -5, into the given equation.
f(-5) = |-5 + 1|
f(-5) = |-4|
f(-5) = 4
Notice that you apply the absolute value symbols after simplifying the terms inside the symbols.
Therefore, when f(x) = |x + 1|, and you need to find f(-5), f(x) = 4.
