Which of these could be the graph of f(x) = ln x + 2?

The shape of that graph is a concave and strictly increasing curve, as shown in the attached graph.

Step-by-step explanation:

The natural logarithm, ln (x), is the inverse of the exponential function and defined in x only for positive real numbers, in addition, it is an irrational number.

From the analytical point of view, it can be defined that for any positive real number x> 0 as the area under the curve y = 1 / t between 1 and x. The natural logarithm is a function with domain of definition of positive real numbers.

Some of the properties of the natural logarithm are: it is a bijective, concave, strictly growing and continuous function

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
