B (t) = 50 (1.4) ^ t
What is the y-intercept of the function?
The intersection with the y-axis of the function you find when x = 0.
In this case we have:
For t = 0:
B (0) = 50 (1.4) ^ 0
B (0) = 50 * (1)
B (0) = 50
Answer:
the y-intercept of the function is:
B (0) = 50
What does this mean in the context of the problem?
You must place the complete statement to answer exactly.
However, in any problem of exponential type, it means the initial quantity of something.
If we refer to the increase in population over time, then the intersection with the y-axis is the initial population.

Step-by-step explanation:
The frame will go around all 4 sides of the painting. That means that the length of each side of the painting will increase by 2.5 inches. The height, <em>h</em>, will now be <em>h</em> + 5 (2.5 inches on the top and the bottom). The width, 2<em>h</em> + 3, will now be 2<em>h</em> + 3 + 5 (again, 2.5 inches on the top and the bottom). The area would be given by
(<em>h</em> + 5)(2<em>h</em> + 3 + 5) = (<em>h</em> + 5)(2<em>h</em> + 8)
Multiplying this, we have:
<em>h</em>*2<em>h</em> + <em /><em>h</em>*8 + <em />5*2<em>h</em> + 5*8 = 2<em>h</em>² + 8<em>h</em> + 10<em>h</em> + 40 = 2<em>h</em>² + 18<em>h</em>² + 40
