Questions & Step-by-Step Solutions
In the function f(x) = |x|, what is the value of f(-3)?
Step 1: Understand the function f(x) = |x|. This means we are looking for the absolute value of x.
Step 2: Identify the value of x we need to use. In this case, x = -3.
Step 3: Apply the absolute value function to -3. The absolute value of a number is its distance from 0 on the number line, without considering direction.
Step 4: Since -3 is negative, its absolute value is 3.
