Question

Use the piecewise function to find f(-2).

f(x) =
A) -4, x ≤ -2
B) -2, -2 < x
C) 1 - 2x, x > 2

Answer 1

To find f(-2) in the given piecewise function, we use part A which applies for x ≤ -2, resulting in f(-2) = -4.

Step-by-step explanation:

To find f(-2), we need to look at the given piecewise function and determine which part of the function applies for x = -2.

• A) -4, x ≤ -2
• B) -2, -2 < x
• C) 1 - 2x, x > 2

Since -2 is equal to the boundary value of the first case of the piecewise function, we use A) for our calculation. Thus, f(-2) = -4. No other parts of the piecewise function are relevant since they apply to different ranges of x.
