===============================================

Work Shown:

Plug x = 8 into the function. Simplify.

f(x) = 5x-15

f(8) = 5*8-15

f(8) = 40-15

f(8) = 25

The input x = 8 leads to the output y = f(x) = 25.

The domain is the set of all allowed x inputs.

The range is the set of all possible y outputs.

The point (x,y) = (8,25) is on the graph of f(x) = 5x-15.
