In the exponential function \( f(x) = 620 \cdot 7.8^x \), the general form of an exponential function is \( f(x) = a \cdot b^x \), where \( a \) is the initial amount (or initial value) and \( b \) is the growth factor.
Comparing the given function with the general form, we can identify:
- The initial amount \( a \) is the coefficient in front of the exponent, which is \( 620 \).
- The growth factor \( b \) is the base of the exponent, which is \( 7.8 \).
So, the initial amount \( a \) is \( 620 \) and the growth factor \( b \) is \( 7.8 \).
The correct pair is:
620, 7.8
8.
Identify the initial amount a and the growth factor b in the exponential function.
f(x) = 620 ∙ 7.8x
620, 7.8
620, 7.8x
7.8, 620
7.8x, 620
