There are two ways to solve the problem: using calculus and algebra. For this, I'll be using the algebraic way. The function is parabolic, thus the minimum value is the ordinate of the vertex. Using completing the square, we could get the vertex of the parabola.
y = x^2 + 4x - 5y = x^2 + 4x + 4 - 5 - 4y = (x + 2)^2 - 9Vertex is (-2, -9).
Therefore, the minimum value is -9.

Present value: P=$420
Annual interest: i=3%=3/100→i=0.03
Compounded monthly→Number of periods per year: n=12
Future Value: F=?
In two months: t=2
F=P(1+i/n)^t
F=$420(1+0.03/12)^2
F=$420(1+0.0025)^2
F=$420(1.0025)^2
F=$420(1.005006250)
F=$422.1026250
Rounded to two decimal places:
F=$422.10
Answer: Option B. $422.10
Answer:
p = y+3
Step-by-step explanation:
152.30(0.15)= 22.845
