Answer 1

Question? :)

Answer 2

The table below shows the values of y for each value of x:


x y
-1 0
-1 -1
-2 2
-2 3


Part A: Does the table represent a relation that is a function? Justify your answer by using the values shown in the table. (4 points)

Part B: The function f(h) shown below represents the number of tennis matches Diana won each month when she practiced tennis for h hours every day:

If f(h) = 3h + 1

Calculate and interpret the meaning of f(3).

Part C: Write an ordered pair to represent the input and output of the function in Part B when Diana practices tennis for b hours every day.

Answer 3

One way in which to recognize a function is this: For any of the input (x-) values, there is exactly one output (y-) value. Look at your table and see whether you can now decide whether the table represents a function or not.

So
f(h) = 3h + 1
f(3) = 3(3) + 1

All you do is when the letter in the parentheses is replaced by a number then you replace the letter with the number. In this case it's:
f(h) = 3h + 1
f(3) = 3(3) + 1
f(3)= 10

Answer 4

It does not represent a function.

Answer 5

A function such as f(x)=x+1 produces ordered pairs representing x- and y-values. If the input to this function is 7, the output is 8. Write the ordered pair (b, f(b)). This is part C

Answer 6

So, what you just explained "A function such as f(x)=x+1 produces...ordered pairs (b,f(b))" is Part C?

Answer 7

A: It does not.

B: f(h) = 3h + 1
f(3) = 3(3) + 1
f(3)= 10

C: (7,8)
