The student solved the problem incorrectly. The student should add 12.7 to both sides of the equation to isolate the variable, y.
Let the required equation be y = mx + c; where y = 1, m = f'(0), x = 0
f(a) = sec(a)
f'(a) = sec(a)tan(a)
f'(0) = sec(0)tan(0) = 0
y = mx + c
1 = 0(0) + c
c = 1
Therefore, required equation is
y = 1.

Answer:None</h2>
Step-by-step explanation:
For any function,any point in the domain has a unique image in the codomain.
For set 
:
from the point 
from the point 
For a same point 
,there are two images.
So, does not represent a function.
