A 2-column table with 3 rows. Column 1 is labeled time elapsed (hours) with entries 2, 4, 7. Column 2 is labeled Distance Run (miles) with entries 13.5, 27.5, 48.5.

Larry recorded his time as he ran. What was his average speed from hour 2 to hour 4?

What was his average speed from hour 4 to hour 7?

Did he speed up or slow down?

it is x=-4

step-by-step explanation:

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.

multiplication is multiplication.   it might feel harder depending on what level of math you are in, but generally it will be the same old stuff, while implementing some new concepts and methods of solving work.
