Answer:

B

Step-by-step explanation:

The graph of a function and its inverse are symmetric with respect with the line y = x.

On each graph you are given, plot the line y = x. If the two functions are symmetric with respect to the line y = x, then the graph does show a function and its inverse.

You will see this is true only for choice B

Simplify the left side of equation so it looks like the right side. cos(x) + sin(x) tan(x) = sec (x)
uranmaximum [27]

Step-by-step explanation:

Consider LHS

\cos(x)  +  \sin(x)  \tan(x)  =  \sec(x)

Apply quotient identies

\cos(x)  +   \sin(x) \times  \frac{ \sin(x) }{ \cos(x) }  =  \sec(x)

Multiply the fraction and sine.

\cos(x)  +  \frac{ \sin {}^{2} (x) }{ \cos(x) }  =  \sec(x)

Make cos x a fraction with cos x as it denominator.

\cos(x)  \times  \cos(x)  =  \cos {}^{2} (x)

so

\frac{ \cos {}^{2} (x) }{ \cos(x) }  +  \frac{ \sin {}^{2} (x) }{ \cos(x) }  =  \sec(x)

Pythagorean Identity tells us sin squared and cos squared equals 1 so

\frac{1}{ \cos(x) }  =  \sec(x)

Apply reciprocal identity.

\sec(x)  =  \sec(x)
