To determine the range of the exponential function given by the equation \( h(x) = 49\left(\frac{2}{7}\right)^x \), we need to consider the behavior of the function as \( x \) varies.
-
Identify the base of the exponential function: The base here is \( \frac{2}{7} \), which is between 0 and 1. As \( x \) increases, \( \left(\frac{2}{7}\right)^x \) approaches 0 but never actually reaches 0.
-
Evaluate the function at specific points:
- For \( x = 0 \): \[ h(0) = 49\left(\frac{2}{7}\right)^0 = 49(1) = 49 \]
- As \( x \) approaches \( \infty \): \[ h(x) \to 49(0) = 0 \]
-
Range of the function: Since \( h(x) \) decreases from \( 49 \) to \( 0 \) but never actually reaches \( 0 \), the function can take any positive value but cannot equal 0.
Given this analysis, the correct inequality describing the range of the function is:
d. \( y > 0 \).
This means the output of the function is always positive.
