To determine the correct equation based on the given points (0, 10) and (1, 10.5), we can analyze the points in relation to the equations provided.
- The point (0, 10) indicates that when \(x = 0\), \(y\) should equal 10.
- The point (1, 10.5) indicates that when \(x = 1\), \(y\) should equal 10.5.
Let's check each option:
-
\(y = 1.05 \cdot (10)^x\):
- For \(x = 0\): \(y = 1.05 \cdot (10)^0 = 1.05 \cdot 1 = 1.05\) (not a match).
-
\(y = -10 \cdot (1.05)^x\):
- For \(x = 0\): \(y = -10 \cdot (1.05)^0 = -10 \cdot 1 = -10\) (not a match).
-
\(y = 10 \cdot (1.05)^x\):
- For \(x = 0\): \(y = 10 \cdot (1.05)^0 = 10 \cdot 1 = 10\) (match).
- For \(x = 1\): \(y = 10 \cdot (1.05)^1 = 10 \cdot 1.05 = 10.5\) (also a match).
-
\(y = 10 \cdot - (1.05)^x\):
- For \(x = 0\): \(y = 10 \cdot - (1.05)^0 = 10 \cdot -1 = -10\) (not a match).
Based on this analysis, the correct equation that matches the points given is:
\(y = 10 \cdot (1.05)^x\).
