To find the values of $g(4)$, $g(-10)$, and $g(0)$, we need to first determine the function $g(x)$.<br /><br />Given that $fg(x) = \frac{1}{2}x + 5$, we can rewrite this as $g(x) = \frac{1}{2}x + 5$.<br /><br />Now, let's find the values of $g(4)$, $g(-10)$, and $g(0)$:<br /><br />a. $g(4)$:<br />Substitute $x = 4$ into the function $g(x)$:<br />$g(4) = \frac{1}{2}(4) + 5$<br />$g(4) = 2 + 5$<br />$g(4) = 7$<br /><br />b. $g(-10)$:<br />Substitute $x = -10$ into the function $g(x)$:<br />$g(-10) = \frac{1}{2}(-10) + 5$<br />$g(-10) = -5 + 5$<br />$g(-10) = 0$<br /><br />c. $g(0)$:<br />Substitute $x = 0$ into the function $g(x)$:<br />$g(0) = \frac{1}{2}(0) + 5$<br />$g(0) = 0 + 5$<br />$g(0) = 5$<br /><br />Therefore, the values are:<br />a. $g(4) = 7$<br />b. $g(-10) = 0$<br />c. $g(0) = 5$
