Find the domain of the vector functions, (), listed below. using interval notation.

a) ()=⟨ln(4),+19‾‾‾‾‾‾√,19−‾‾‾‾‾√⟩
b) ()=⟨−9‾‾‾‾‾√,sin(2),2⟩
c) ()=⟨ −9,2−4‾‾‾‾‾‾√,1/3⟩

Attached is the solution for a supposed question.hope it helps

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.
