Answer:
a = 5120
b = 1.25
Step-by-step explanation:
Let the exponential function representing the given table is,
f(x) = 
Here, f(x) = Number of views
x = Number of weeks
We choose two points from the given table and satisfy the equation of the function.
Let the points are (0, 5120) and (1, 6400)
For a point (0, 5120),
f(0) = a(b)⁰ = 5120
a = 5120
Now for the second point (1, 6400),
6400 = 5120(b)¹
b = 
b = 1.25
Therefore, a = 5120 and b = 1.25 are the values.
Answer:
1/16
Step-by-step explanation:
2^-4
We know that a^ -b = 1/ a^b
2^-4 = 1/2^4
2^4 =16
so 1/2^4 = 1/16
The question asks for a vertical line, and if it is vertical, it cannot be y = ... because that is horizontal. We also know it passes through the x-coordinate of -4, so the answer is x = -4.
