A function $f: [-4, 4] \to [0, 4]$ is given by $f(x) = \sqrt{16-x^2}$. Show that $f$ is an onto function but not a one-one function. Further, find all possible values of 'a' for which $f(a) = \sqrt{7}$. [All India 2023]

Prove that the relation $R$ in the set of integers $Z$ defined as $R = \{(a, b) : 2 \text{ divides } (a + b)\}$ is an equivalence relation. Also, determine $[3]$. [All India 2024]

34. (a) If N denotes the set of all natural numbers and R is the relation on $N \times N$ defined by $(a, b) R (c, d)$, if $ad(b+c)=bc(a+d)$. Show that R is an equivalence relation.

Check whether the relation $R$ in $R$ defined by $R = \{(a, b) : a \le b^3\}$ is reflexive, symmetric or transitive. [All India 2024]

Let $f, g : N - \{1\} \to N$ be functions defined by $f(a) = \alpha$, where $\alpha$ is the maximum of the powers of those primes $p$ such that $p^\alpha$ divides $a$, and $g(a) = a + 1$, for all $a \in N - \{1\}$. Then, check whether the function $f + g$ is one-one or onto. [Competency]

A relation $R$ in set $A = \{1, 2, 3\}$ is defined as $R = \{(1, 1), (1, 2), (2, 2), (3, 3)\}$. Find ordered pair in $R$ shall be removed to make it an equivalence relation in $A$.
