Answer:
30 points wow
Step-by-step explanation:
thx anyways
480 is 100%
48 = 10%
480 = 100%
- Yes, the height, h(t) of a ball t seconds after it's dropped from the third floor of a building is a function.
- No, table B is not a function because no function can have the same y-values (5) for different x-values (1 and 8).
- Yes, table C is a function because it has different y-values for same x-values.
- Yes, graph D is a function because it has different y-values for same x-values.
<h3>What is a function?</h3>
A function can be defined as a mathematical expression which is used to define and represent the relationship that exists between two or more variables.
<h3>The types of function.</h3>
In Mathematics, there are different types of functions and these include the following;
- Piece-wise defined function.
For this exercise, we would indicate whether or not each of the above mathematical relation represents a function:
- Yes, the height, h(t) of a ball t seconds after it's dropped from the third floor of a building is a function.
- No, table B is not a function because no function can have the same y-values (5) for different x-values (1 and 8).
- Yes, table C is a function because it has different y-values for same x-values.
- Yes, graph D is a function because it has different y-values for same x-values.
In conclusion, we can infer and logically deduce that a function maps every x-value in a valid domain to a single y-value only.

Step-by-step explanation:
soln
given
y=2x+3 -----(i)
y=-x-9 ------(ii)
now, putting value of equation (i) in (ii)
y= -x-9
or, 2x+3 = -x-9
or, 2x+x = 9-3
or, 3x = 6
or, x = 6/3
or, x = 2
again,
y = 2x+3
or, y = 2×2+3
or, y = 7
therefore, value of X and Y are 2 and 7 respectively.

Step-by-step explanation:
1. The limit of f+g is the sum of the limits: lim(f)+lim(g). Unfortunately, the limit of g from the left (2) is different from the limit of g from the right (1) at x=1. Hence, the limit of g does not exist, so the limit of f at that point (2) is irrelevant.
2. lim(f+g) = lim(f)+lim(g) = 1 + 2 = 3. Both functions are defined and continuous at x=2, so their values can be read from the graphs.
3. lim(f·g) = lim(f)·lim(g) = 0·(3/2) = 0. Both functions are defined and continuous at x=0, so their values can be read from the graphs. We doubt that g(0) = 3/2 exactly, but it doesn't matter since f(0) = 0.
4. lim(f/g) = lim(f)/lim(g) = 0/(3/2) = 0. See the explanation for 3, immediately above.
5. f(-1) = -2, which is the limit aproaching either from the left or right. √(3-2) = 1. The function f is defined and continuous at x=-1, so its value can be read from the graph.
