Use the function rule f(x)=x*|-1|^x. Find the output f(2).
A.4
B.3
C.-2
D.2
sorry never mind its d. thanks anyways :)
To find the output of a function, you need to substitute the given value into the function rule.
In this case, you want to find the output of the function f(x) = x * |-1|^x when x = 2.
Step 1: Substitute x = 2 into the function rule:
f(2) = 2 * |-1|^2
Step 2: Simplify the expression inside the absolute value:
|-1|^2 = 1^2 = 1
Step 3: Substitute the simplified expression back into the original function:
f(2) = 2 * 1 = 2
Therefore, the output of the function f(2) is 2.
The correct answer for f(2) is D. 2.
