Answer

Final Answer: The y-intercept of the function $y=(2.5)^{x}-6$ is $\boxed{y=-5}$

Steps

Step 1 ：The y-intercept of a function is the point where the graph of the function intersects the y-axis. This happens when x = 0. So, to find the y-intercept, we need to substitute x = 0 into the function and solve for y.

Step 2 ：Substitute x = 0 into the function y = (2.5)^x - 6

Step 3 ：y = (2.5)^0 - 6

Step 4 ：y = 1 - 6

Step 5 ：y = -5

Step 6 ：Final Answer: The y-intercept of the function $y=(2.5)^{x}-6$ is $\boxed{y=-5}$
