The y-value of the vertex is positive 3, as shown by the +3 on the right hand side of the equation, and the x-value is -1, from the (x+1)^2 (remember, when the number is inside the brackets, flip the sign) The vertex would be (-1, 3)
If you are looking for a rigorous answer (calculus), we must find the mininum point of the equation: f(x) = (x+1)^2 + 3 f
f'(x) = 2(x+1) = 2x + 2
2x + 2 = 0
x = -1
f(1) = (-1 + 1)^2 + 3
f(1) = 0 + 3 = 3
(-1, 3)
Answer:
c = 10h
Step-by-step explanation:
c = 8h
Where,
c = Total amount she should charge a customer
h = Number of hours
8 = amount charged per hour of babysitting
A. 8 is the constant of proportionality and it means Nila charges $8 per hour of babysitting
B. If she decides to increase the rate she charges customers by $2 per hour, then the new equation she should use to determine how much to charge her customers is:
c = (8 + 2)h
c = 10h
