Quadratic Equation
When it comes to the concept of polynomial equations, quadratic equations can be said to be a special case. What does solving a quadratic equation mean? We will understand the quadratics and their types once we are familiar with the polynomial equations and their types.
Demand and Supply Function
The concept of demand and supply is important for various factors. One of them is studying and evaluating the condition of an economy within a given period of time. The analysis or evaluation of the demand side factors are important for the suppliers to understand the consumer behavior. The evaluation of supply side factors is important for the consumers in order to understand that what kind of combination of goods or what kind of goods and services he or she should consume in order to maximize his utility and minimize the cost. Therefore, in microeconomics both of these concepts are extremely important in order to have an idea that what exactly is going on in the economy.
(a) Find (m + r)(3).
(b) Find (m − r)(3).
(c) Find (m + r)(4).
(d) Find (m − r)(4).
![The text above the graph reads:
"The graph of function \( m \) below gives the average score on the mathematics portion of the SAT college entrance exam, the graph of function \( r \) gives the average score on the critical reading portion, and \( x \) represents the number of years since 2000."
The graph is titled "U.S. Average SAT Scores" and it displays two line graphs on a grid.
**Graph Details:**
- **x-axis:** Labeled "Years since 2000", with values from 0 to 9.
- **y-axis:** Labeled "Points Scored", with values from 500 to 522, marked every two points.
**Functions:**
1. **Function \( m \) (Mathematics Scores):**
- Plotted with a magenta line.
- Starts slightly above 518 in year 0.
- Peaks at 520 between years 2 and 3.
- Ends at approximately 514 in year 9.
2. **Function \( r \) (Critical Reading Scores):**
- Plotted with a blue line.
- Starts at 504 in year 0.
- Peaks at 510 between years 4 and 5.
- Ends just above 500 in year 9.
The graph effectively shows a fluctuation in scores over the years, with mathematics scores generally higher than critical reading scores.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F489733d2-878d-41cc-ad67-e5e585d0abfc%2Faabf851b-33e4-4e51-b75e-93839493dc39%2Fbem1xyf_processed.png&w=3840&q=75)
