Natural Logarithm
General Logarithm
Common Logarithm
None of these
If f(x) = x3 -2x2+4x -1, then f(1+x) =
x3-x2+ 3x +2
x3+ x2+ 3x +2
x3+ x2 -3x +2
x3+ x2+ 3x +2
If f(x) = x3 -2x2+4x -1, then f(-2)=
20
-25

Let f(x) = 4 – x, g(x) = 2x + 1, then fog(x) =
2 + 3x
5 + 2x
3 – 2x
2 – 3x
If f(x) = 2x + 1, then fof(x) equals
4x -1
4x + 3
4x – 3
4x + 1
The term function was recognized by a German Mathematician:
Newton
Lagrange
Cauchy
Leibniz
If f(-x) = f(x), then f(x) is called
