To find the values of \( f(x) \) for the given function \( f(x) = \sqrt{x} + 1 \), we need to substitute the given values of \( x \) into the function and simplify.<br /><br />a. \( f(9) \):<br />\[ f(9) = \sqrt{9} + 1 = 3 + 1 = 4 \]<br /><br />b. \( f(4) \):<br />\[ f(4) = \sqrt{4} + 1 = 2 + 1 = 3 \]<br /><br />c. \( f(1) \):<br />\[ f(1) = \sqrt{1} + 1 = 1 + 1 = 2 \]<br /><br />So, the answers are:<br />a. \( f(9) = 4 \)<br />b. \( f(4) = 3 \)<br />c. \( f(1) = 2 \)
