Question

fill in the table using the function rule y = 4x + 3 (table with x values 4, 7, 0, 9 and empty y cells)

Explanation:

Step1: For \( x = 4 \)

The function is \( y = 4x + 3 \). Substitute \( x = 4 \) into the function:
\( y = 4\times4 + 3 = 16 + 3 = 19 \)

Step2: For \( x = 7 \)

Substitute \( x = 7 \) into \( y = 4x + 3 \):
\( y = 4\times7 + 3 = 28 + 3 = 31 \)

Step3: For \( x = 0 \)

Substitute \( x = 0 \) into \( y = 4x + 3 \):
\( y = 4\times0 + 3 = 0 + 3 = 3 \)

Step4: For \( x = 9 \)

Substitute \( x = 9 \) into \( y = 4x + 3 \):
\( y = 4\times9 + 3 = 36 + 3 = 39 \)

Answer:

When \( x = 4 \), \( y = 19 \); when \( x = 7 \), \( y = 31 \); when \( x = 0 \), \( y = 3 \); when \( x = 9 \), \( y = 39 \)
