Question

Consider the function f(x)=−x+4. Find the values of f(−2) and f(1).

a) f(−2)=6
b) f(−2)=2
c) f(−2)=−2
d) f(−2)=−6

Answer 1

After evaluating the function f(x) = -x + 4 for x = -2 and x = 1, the value of f(-2) is 6 and f(1) is 3.

Step-by-step explanation:

The question is asking us to evaluate the function f(x) = -x + 4 for two different values of x: when x is -2 and when x is 1.

• For f(-2), we substitute x with -2: f(-2) = -(-2) + 4 = 2 + 4 = 6.
• For f(1), we substitute x with 1: f(1) = -(1) + 4 = -1 + 4 = 3.

Therefore, the correct answer for f(-2) is 6, and for f(1) the value is 3.
