Let f(x)= 14x - 3 and g(x) = Find (f+g)(x), (f-g)(x), (fg)(x), and
(x). Give the domain of each.
х
(f+g)(x) =(Simplify your answer.)

after simplifying it i got: -36.25 as my answer. hope that !

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
