Answer:
g(x) = 86·1.011055^x
Step-by-step explanation:
So we don't confuse ourselves, we'll call the growth function by day g(x). If x is to represent days, then x/7 represents weeks, and we can write ...
g(x) = f(x/7) = 86·1.08^(x/7)
g(x) = 86·(1.08^(1/7))^x
g(x) = 86·1.011055^x
3x³+6x²+9x+10
or
6x³+9x²+3x+5

the constant can be any number.
For this case we have the following system of equations:
y = x + 5
y = -2x - 1
Substituting the point (-2, 3) we have:
For Line C:
y = x + 5
3 = -2 + 5
3 = 3
The line goes through this point.
For Line D:
y = -2x - 1
3 = -2 (-2) - 1
3 = 4 - 1
3 = 3
The line goes through this point.
Answer:
(-2, 3), because both lines pass through this point
