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). (4 points)

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. (2 points)

1 answer

There isn't a table in Part A.

This means that if Diana practices for 3 hours she will win 10 tennis matches.

Part B = 10

And for Part C just plug in a number for b and put it in place for x.

For example if she practiced for 2 hours the equation would look like this 3(2)+1 , which equal 7. Make sense?
