what is the value of a for the exponential function in the graph represented in the form of f(x)=a(b^x)? Zoom in the photo bcz i

nekit [7.7K]

Answer:

$a = 3$

Step-by-step explanation:

To determine the value of $a$ , we want $b^x$ to be 1, so that $f(x) = a \times 1$ . Notice that if $x = 0$ , then $f(0) = a \times (b^0) = a$ , so the value of $a$ is simply $f(0)$ . From the graph, it appears that $f(0) = 3$ , so therefore $a = 3$ .
