Given that \(f(x) = \frac{5x^2-9.2x^4}{25.7+x^6}\) and we need to compare Quantity A ( f(2.38) ) and Quantity B ( f(-2.38) )
Now, f(x) has only even powers of x in numerator and denominator. So if we same value of x but with different sign then f(x) is going to give the same value in both the cases
And Quantity A = f(2.8) and Quantity B = f(-2.8)
=> Quantity A = Quantity B
So, Answer will be C
Hope it helps!
