যদি f(x) = x2 - 2 |x| এবং g(x) = x2 + 1 হয়, তবে fog (2) এর মান হবে-
5
15
25
0
(fog) (2) =f{g(2)}=f(22+1)=f(5)=52−2∣5∣=15 =\mathrm{f}\{\mathrm{g}(2)\}=\mathrm{f}\left(2^{2}+1\right)=\mathrm{f}(5)=5^{2}-2|5|=15 =f{g(2)}=f(22+1)=f(5)=52−2∣5∣=15
If AAA and BBB have nnn elements in common, then the number of elements common to A×BA\times BA×B and B×AB\times AB×A is
f(x)= x−2 \sqrt{x - 2} x−2 এবং g(x)=x2+1 হলে fog এর ডোমেন কত ?
If g(f(x))=∣sinx∣g(f(x))= |\sin x|g(f(x))=∣sinx∣ and g(f(x))=sin2x,g(f(x))= \sin ^2 \sqrt{x},g(f(x))=sin2x, then-
f(x)=x4–x2+14 f{\left ( x \right )} = x^{4} – x^{2} + \frac{1}{4} f(x)=x4–x2+41 এবং g(x)=x+1 g{\left ( x \right )} = \sqrt{x + 1} g(x)=x+1 হলে fog(x) = কত?
