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.

Answer:
y = 0.5cos(4(x+π/2)) -2
Step-by-step explanation:
The centerline of the oscillation is at -2, so only the 2nd and 4th choices are viable.
The multiplier of x is computed from (2π)/period. One period is π/2, so the multiplier of x is ...
... 2π/(π/2) = 4 . . . . . matching the 2nd selection.
The horizontal offset in the second equation (π/2) is of no consequence, as it is one full period of the function.
The peak-to-peak amplitude of the oscillation is 1 unit, so the multiplier of the cosine function (which usually has a peak-to-peak value of 2 units) is 0.5. Every offered answer has that characteristic.
The appropriate choice is the 2nd one:
... y = 0.5cos(4(x+π/2)) -2
