Open in App

Solution

Value of polynomial:
Substitute the value in the given function to compute $g (3)$ .
Given a function $g (x) = x^{2} - x$ .
Substitute $x = 3$ in the function,
$g (x) = x^{2} - x \Rightarrow g (3) = 3^{2} - 3 \Rightarrow g (3) = 9 - 3 \Rightarrow g (3) = 6$
Hence, the value is $g (3) = 6$ .
