Question

Luke is keeping track of the total number of hours he exercises. He started the summer having already put in 15 hours, and he then exercises 7 hours each week. The function to keep track of his exercise is f(x) = 7x + 15. What do the f(x) and x represent in Luke's situation?

Answer 1

Answer:

the x is the number of weeks he has exersized and the f(x) is the value of the function

Hope this helps ;)

Answer 2

Answer:

f of x/f(x)= represents "a formula, named f, has x as its input variable". It does not mean "multiply f and x"!

X represents the number of weeks he has exercised. So if he practiced for 6 weeks then you multiply that times 7 hours each week. PLUS the 15 he originally started with. You must add that on at the end.

If you are also looking to solve for X the answer to this equation is f(x)−7x=15

Hope this helps!
