Find an equation of the tangent line to the curve at the given point. y=sqrt(x) (1,1) ive never been good with these equations and the square root is confusing me.

Equation of a tangent line of a curve is:
y- y0 = f´ (x0) (x - x0 ).   In this case: x0=1, y0=1
f´(x)=(Derivation)
f´(x0)=
y - 1 = 1/2 ( x - 1 )
y - 1 = 1/2 x - 1/2
y = 1/2 x - 1/2 + 1
y =   

Deja qué x = longitud6(x) = 48cm^2divide por 6: x = 8la área de longitud es 8 cm.

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
