Question

an exponential function is graphed below. choose the correct answer from each drop - down menu to complete the function that best represents the graph. $f(x)=15 (0.60)^{x}$ (with drop - down options for the base: 0.60, 1.13, 1.20)

Explanation:

Step1: Identify the exponential form

Exponential function: $f(x)=a \cdot b^x$

Step2: Find initial value $a$

At $x=0$, $f(0)=a=15$ (matches dropdown)

Step3: Verify base $b$

The graph is decreasing, so $0

Answer:

$f(x)=15 \cdot (0.60)^x$
A. 15, B. 0.60
