f(x) = cos x + sin x is ____________ function
Nor the even nor odd
Odd
Even
Both even & odd
The equation of the type x=f(t) and y=g(t) are called:
Parametric equations
Reciprocal equations
None of these
Implicit functions
If f(-x) = -f(x) for all x in the domain of f, then f is
Linear function
Odd function
Identity function
Even function
If F(x) = x contx than f(x) is:
even function
odd function
neither even nor odd
quadratic function
Let f(x) = 4 – x, g(x) = -2, then fog (x) =
2
8
6
5
If f : X
Range of f
Both (a) & (b)
None of thsese
Domain of f
Explicit form of y – x2 – 2x + 1 = 0 is ————————-
None
y=x2 + 2x-1
y-x2 = 2x-1
2x + x2 = y + 1
Which one is an identity function?
f(x) = g(x)
f(x) = 1
f(x) = x
f(x) = x2
lim Sin2x/x =………
0
1
none of these
2

Odd function
Even function
Linear function
Quadratic function
