Solution

Consider the given function

$f (x) = x^{2} + x$

$D = R$

$s o t h a t D (- \infty, \infty), R (0. \infty)$

$p u t t h a n y = x^{2}$

$∴ D (- \infty, \infty), R (- \infty, - 1)$

Hence this is the answer.

f (x) = ⎧ ⎪ ⎪ ⎨ ⎪ ⎪ ⎩ \begin{matrix} x^{2} & x < 0 x & 0 \leq x \leq 1 \frac{1}{x} & x > 1 \end{matrix}

f(x)= $x^{2}$ for x < 2

g(x)= $x^{2}$ for x > -1

Range of f(x)= range of g(x)

The range of f(x) = $\frac{x^{2} + x + 1}{x^{2} + x - 1}$

f (x) = \frac{x^{2} - x + 1}{x^{2} + x + 1}
