Use the function rule ƒ(x) = x • |–1|x. Find the output ƒ(2).
4
• 3
• –2
• 2
really? Just plug and chug.
ƒ(2) = 2 • |–1|2 = 4
Of course, you may have meant
ƒ(x) = x • |–1|^x
in which case
ƒ(2) = 2 • |–1|^2 = 2
heck, for all I know, you may have meant ƒ(x) = x • (–1)x since you are otherwise so careless.
To find the output ƒ(2) of the function ƒ(x) = x • |–1|x, we need to substitute x with 2 in the function and evaluate the expression.
First, we substitute x with 2:
ƒ(2) = 2 • |–1|2
Next, we evaluate the absolute value of -1, which is equal to 1:
ƒ(2) = 2 • 1 • 2
Finally, we simplify the expression:
ƒ(2) = 4
Therefore, the output ƒ(2) is 4.
To find the output ƒ(2) using the function rule ƒ(x) = x • |–1|x, we substitute x = 2 into the function:
ƒ(2) = 2 • |–1|2
The absolute value of –1 is 1, so we simplify further:
ƒ(2) = 2 • 1 • 2
Now, we multiply to obtain the final answer:
ƒ(2) = 4
Therefore, the output ƒ(2) is 4.
