To determine which equation correctly describes the function in the table, we need to analyze the given pairs of \( (x, y) \):
- When \( x = 0 \), \( y = -2 \)
- When \( x = 2 \), \( y = 4 \)
- When \( x = 4 \), \( y = 10 \)
- When \( x = 6 \), \( y = 16 \)
We'll test each proposed function to confirm which one fits the values in the table.
-
For \( f(x) = x - 2 \):
- \( f(0) = 0 - 2 = -2 \) (correct)
- \( f(2) = 2 - 2 = 0 \) (incorrect, should be 4)
- This function does not match.
-
For \( f(x) = 2x \):
- \( f(0) = 2(0) = 0 \) (incorrect, should be -2)
- This function does not match.
-
For \( f(x) = 3x - 2 \):
- \( f(0) = 3(0) - 2 = -2 \) (correct)
- \( f(2) = 3(2) - 2 = 6 - 2 = 4 \) (correct)
- \( f(4) = 3(4) - 2 = 12 - 2 = 10 \) (correct)
- \( f(6) = 3(6) - 2 = 18 - 2 = 16 \) (correct)
- This function matches all points.
-
For \( f(x) = 2x + 4 \):
- \( f(0) = 2(0) + 4 = 4 \) (incorrect, should be -2)
- This function does not match.
The correct function that describes the relationship in the table is:
\( f(x) = 3x - 2 \)
