(Type an exact answer.)
Solution
Solution Steps
Step 1: Identify the General Form of the Exponential Function
The general form of an exponential function is \( y = ab^x \), where \( a \) is the initial value (y-intercept) and \( b \) is the base of the exponential function.
Step 2: Determine the Initial Value \( a \)
From the graph, we can see that when \( x = 0 \), \( y = -1 \). Therefore, the initial value \( a \) is -1.
Step 3: Use Another Point to Find the Base \( b \)
We can use the point (1, -6) to find the base \( b \). Substitute \( x = 1 \) and \( y = -6 \) into the equation \( y = ab^x \):
