Question

complete the table for the function ( y = x^2 ). for each question, choose the correct value for the yellow cell.
( y = x^2 )

input	output	calculation
-2	a. (yellow cell)
-1	b.
0	c.
1	d.
2	e.
3	f.

options for a. (and other yellow cells): 4, -4, 8

Explanation:

Step1: Identify the function

The function given is \( y = x^2 \). We need to find the output (y - value) when the input (x - value) is - 2 (for the yellow cell 'a').

Step2: Substitute x=-2 into the function

Substitute \( x=-2 \) into \( y = x^2 \). So we calculate \( y=(-2)^2 \).

Step3: Calculate the value

We know that the square of a negative number is positive. So \( (-2)^2=(-2)\times(-2) = 4 \).

Answer:

The value of the yellow cell (a) is 4.
