1.Suppose fff is defined from R→[−1,1]\mathbb{R} \to [-1, 1]R→[−1,1] as f(x)=x2−1x2+1f(x) = \frac{x^2 - 1}{x^2 + 1}f(x)=x2+1x2−1 where R\mathbb{R}R is the set of real numbers. Then the statement which does not hold isa.fff is many one ontob.fff increases for x>0x > 0x>0 and decreases for x<0x < 0x<0c.minimum value is not attained even though fff is boundedd.the area included by the curve y=f(x)y = f(x)y=f(x) and the line y=1y = 1y=1 is π\piπ sq. unitsLogin to continueOnly logged in users canattempt or see the solution.
