What is the y-intercept of the graph of `f(x)=12.8(6.7)^{x}` ?

(6.7,0)
(12.8,0)
(0,6.7)
(0,12.8)

The y-intercept is the point where the graph of a function intersects the y-axis. It is the point at which x = 0.

For the given function f(x) = 12.8(6.7)^x, when x = 0, the equation becomes:
f(0) = 12.8(6.7)^0
= 12.8(1) (Any number raised to the power of 0 is 1)
= 12.8

Therefore, the y-intercept is (0, 12.8).
