Question

Use the table to answer the question.

X / f(x)
-1
0
1
2

Finish creating the input-output table for the function f(x)=-(x+1)^2+4. Which of the given x values produces the largest output for the function?

x=0
x=-1
x=1
x=2

Answer 1

The completed table is:

X / f(x)
-1 / 4
0 / 3
1 / 0
2 / -3

From the table, it can be seen that x = -1 produces the largest output for the function f(x) = -(x+1)^2 + 4. The output value is 4 when x = -1.
