Let's examine the three functions from the image you've uploaded. Each function seems to require filling out a table based on the given inputs $x$. I'll go through each one step by step.

Function 1: $f(x) = x^2$

You need to square each value of $x$ and fill in the table.

$f(x) = x^2$

• For $x = -3$, $f(x) = (-3)^2 = 9$
• For $x = -2$, $f(x) = (-2)^2 = 4$
• For $x = -1$, $f(x) = (-1)^2 = 1$
• For $x = 0$, $f(x) = (0)^2 = 0$
• For $x = 1$, $f(x) = (1)^2 = 1$
• For $x = 2$, $f(x) = (2)^2 = 4$
• For $x = 3$, $f(x) = (3)^2 = 9$

Function 2: $f(x) = x^2 - 5$

Here, after squaring $x$, subtract 5.

$f(x) = x^2 - 5$

• For $x = -1$, $f(x) = (-1)^2 - 5 = 1 - 5 = -4$
• For $x = 0$, $f(x) = (0)^2 - 5 = 0 - 5 = -5$
• For $x = 1$, $f(x) = (1)^2 - 5 = 1 - 5 = -4$
• For $x = 2$, $f(x) = (2)^2 - 5 = 4 - 5 = -1$
• For $x = 3$, $f(x) = (3)^2 - 5 = 9 - 5 = 4$

Function 3: $f(x) = -3(x + 1)^2 + 2$

First, add 1 to $x$, square the result, multiply by -3, and finally add 2.

$f(x) = -3(x + 1)^2 + 2$

• For $x = -3$, $f(x) = -3((-3 + 1)^2) + 2 = -3((-2)^2) + 2 = -3(4) + 2 = -12 + 2 = -10$
• For $x = -2$, $f(x) = -3((-2 + 1)^2) + 2 = -3((-1)^2) + 2 = -3(1) + 2 = -3 + 2 = -1$
• For $x = -1$, $f(x) = -3((-1 + 1)^2) + 2 = -3(0^2) + 2 = 0 + 2 = 2$
• For $x = 0$, $f(x) = -3((0 + 1)^2) + 2 = -3(1^2) + 2 = -3(1) + 2 = -3 + 2 = -1$
• For $x = 1$, $f(x) = -3((1 + 1)^2) + 2 = -3(2^2) + 2 = -3(4) + 2 = -12 + 2 = -10$
