Final answer:
To evaluate the function f(x) at x = -3, substitute -3 into the equation to get f(-3) = -3 + 2, which simplifies to -1.
Step-by-step explanation:
To evaluate f(x) = x + 2 for x = -3, simply substitute -3 into the equation in place of x. This results in the operation -3 + 2.
Step 1: f(-3) = (-3) + 2
Step 2: f(-3) = -1
Therefore, when x equals -3, the value of the function f(x) is -1.
The process of substituting a specific value into a function is a fundamental step in understanding how the function behaves at that particular point.
In summary, evaluating a function involves substituting a specific value for the variable and computing the corresponding output. This is a fundamental concept in understanding the behavior of functions and is crucial in calculus, algebra, and many other areas of mathematics.
