The image shows a math problem related to a non-linear demand and supply function. Here's the content extracted from the image:

Functions:

• Supply function: $P_s = Q^2 + 6Q + 9$
• Demand function: $P_d = Q^2 - 10Q + 25$

Questions:

• (a) Draw the graph of the functions for the interval $Q = 0$ to $Q = 5$.
• (b) Find the equilibrium point for price and quantity.

Let's break it down:

1. (a) Graph the Functions: You are asked to graph the supply and demand functions within the interval $Q = 0$ to $Q = 5$. You can plot the two functions and observe where they intersect within this interval.

2. (b) Find the Equilibrium Point: The equilibrium occurs when the quantity supplied equals the quantity demanded, which means setting $P_s = P_d$, and solving for $Q$.

Solving for the equilibrium point:

Equating the two functions:

$Q^2 + 6Q + 9 = Q^2 - 10Q + 25$

Simplifying:

$6Q + 9 = -10Q + 25$ $16Q = 16$ $Q = 1$

Now substitute $Q = 1$ into either function to find the price:

For $P_s$: $P_s = (1)^2 + 6(1) + 9 = 1 + 6 + 9 = 16$

Therefore, the equilibrium point is $Q = 1$ and $P = 16$.
