A) \[(1,\infty )\]
B) \[\left( 1,\frac{11}{7} \right)\]
C) \[\left( 1,\frac{7}{3} \right)\]
D) \[\left( 1,\frac{7}{5} \right)\]
Correct Answer: C
Solution :
\[\because \] \[f(x)=1+\frac{1}{{{\left( x+\frac{1}{2} \right)}^{2}}+\frac{3}{4}}\] \[\therefore \] Range \[=\left( 1,\frac{7}{3} \right)\]You need to login to perform this action.
