Answer:
Keiko will have 200 subscribers first.
Step-by-step explanation:
Function describing the relation between the number of subscribers and number of months for Keiko is,
K = m² + 10
Where K = Number of subscribers
m = Number of months
If the number of subscribers are K = 200,
200 = m² + 10
m² = 200 - 10
m = √190
= 13.78
≈ 13.8 months
Relation between subscribers and number of months for Jayden is given by the table attached.
Let the function is,
K = mx + b
Where K = number of subscribers
m = slope of the function
x = number of months
b = y-intercept
Slope of the linear function (from the table attached) is,
m = [tex]\frac{56-48}{1-0}[/tex]
= 8
y-intercept 'b' = Value of the function at x = 0
= 48
Therefore, function will be,
K = 8x + 48
200 = 8x + 48
8x = 200 - 48
x = 19 months
Therefore, Keiko will have 200 subscribers first.
