Question

fill in the table using this function rule.
y = -4x + 1
table with x values -2, 0, 2, 4 and empty y cells, along with two buttons (undo and close)

Explanation:

Step1: Substitute \( x = -2 \) into \( y = -4x + 1 \)

\( y = -4\times(-2) + 1 = 8 + 1 = 9 \)

Step2: Substitute \( x = 0 \) into \( y = -4x + 1 \)

\( y = -4\times0 + 1 = 0 + 1 = 1 \)

Step3: Substitute \( x = 2 \) into \( y = -4x + 1 \)

\( y = -4\times2 + 1 = -8 + 1 = -7 \)

Step4: Substitute \( x = 4 \) into \( y = -4x + 1 \)

\( y = -4\times4 + 1 = -16 + 1 = -15 \)

Answer:

When \( x = -2 \), \( y = 9 \); when \( x = 0 \), \( y = 1 \); when \( x = 2 \), \( y = -7 \); when \( x = 4 \), \( y = -15 \)

The filled table is:

\( x \)	\( y \)
0	1
2	-7
4	-15
