1. What is a function?
"In mathematics, a function is a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output. An example is the function that relates each real number x to its square x2<span>."
</span>2. What is the difference between a linear and non-linear function?
"The equation of a linear function has no exponents higher than 1, and the graph of a linear function is a straight line. The equation of a nonlinear function has at least one exponent higher than 1, and the graph of a nonlinear function<span> is a curved line."
</span>
<span>3. Constant Interval, and how does it appear on a graph
</span>Definition:
"Determine the intervals on which a function is increasing, decreasing or constant<span> by looking at a graph. Determine if a function is even, odd, or neither by looking at a graph. Determine if a function is even, odd, or neither given an equation."
How does it appear on a graph?
</span>
"Functions can either be constant, increasing as x increases, or decreasing as x<span> increases."
</span>
<span>4. Identifying the rate of change
</span>
Yes, you can:
"Consider the line y = 2x + 1, shown at the right. Notice that this slope will be the same if the points (1,3) and (2, 5) are used for the calculations. For straight lines, therate of change<span> (slope) is constant (always the same). For every one unit that is moved on the x-axis, two units are moved on the y-axis."
</span>
<span>5. Determining if it is a linear function or not
</span>
"A linear function<span> is in the form y = mx + b or f(x) = mx + b, where m is the slope or rate of change and b is the y-intercept or where the graph of the line crosses the y axis. You will notice that this </span>function<span> is degree 1 meaning that the x variable has an exponent of 1."

Answer:
90.6
Step-by-step explanation:
I think you have the first line incorrect. You show below that 10 students scored 90, so the first line is that 2 students scored 100, not 90. The line with the score of 90 is missing the number of students, but we can find it out. Call that number x for now.
Two students scored 100 each 2
x students scored 95 on each test x
ten students scored 90 on each test 10
three students score 80 on each test 3
and one student scored 70 <u> + 1 </u>
x + 16
There are x + 16 students accounted for. The total number of students is 25.
x + 16 = 25
x = 9
9 students scored 95 on each test.
Now add up all the points scored by all students.
Two students scored 100 each (2 * 90) 200
9 students scored 95 on each test (9 * 95) 855
ten students scored 90 on each test (10 * 90) 900
three students score 80 on each test (3 * 80) 240
and one student scored 70 (1 * 70) <u> + 70 </u>
Sum of all points: 2245
Now we find the average grade by dividing the sum of the points by the number of students.
average = sum/number = 2265/25 = 90.6
Answer:
Step-by-step explanation:
9^2+10^2=c^2
81+100=c^2
181=c^2
=c
