Question

16. Consider the following function: f(x) = Ix-1I, -2≤x≤0

f(x) = x+3 0≤x≤2
• Evaluate f(-2), f(0) and f(2).

Answer 1

To evaluate the function at different values of x, substitute the values into the function expression. f(-2) = -2, f(0) = 1, f(2) = 5.

Step-by-step explanation:

To evaluate the function f(x) at different values of x, we substitute the given values of x into the function expression.

For f(-2), we have f(-2) = I(-2)-1I. Since -2 is less than 0, this becomes f(-2) = -(-2)-1 = -1-1 = -2.

Similarly, for f(0), we have f(0) = I0-1I. Since 0 is also less than 0, this becomes f(0) = -(0-1) = -(-1) = 1.

Finally, for f(2), we have f(2) = 2+3 = 5.
