For the first one we see that the shape is that of a parabola and is translated down a few units, We can eliminate linear, exponential
and looking at the general shapes of quadratic and polynomial functions we can conclude that the graph is from a quadratic equation


So Answer is: (2) quadratic

Sec (a) + tan (a) = sec (a) – tan (a)
Mariulka [41]

Answer:

a = π n for n element Z

Step-by-step explanation:

Solve for a:

sec(a) + tan(a) = sec(a) - tan(a)

Subtract sec(a) - tan(a) from both sides:

2 tan(a) = 0

Divide both sides by 2:

tan(a) = 0

Take the inverse tangent of both sides:

Answer:  a = π n for n element Z
