question 187

Multiple Choice

Find a formula for the slope of the graph of $f$ at the point $( x , f ( x ) )$ .Then use it to find the slope at the given point. $f ( x ) = \sqrt { x - 1 } , \quad ( 17,4 )$

• A) \(\begin{array} { l }
• m = \frac { 1 } { \sqrt { x - 1 } } \\
• \text { At } ( 17,4 ) , m = \frac { 1 } { 8 }
• \end{array}\)
• B) \(\begin{array} { l }
• m = \frac { 1 } { 2 \sqrt { x - 1 } } \\
• \text { At } ( 17,4 ) , m = \frac { 1 } { 8 }
• \end{array}\)
• C) \(\begin{array} { l }
• m = \frac { 1 } { 2 \sqrt { x - 1 } } \\
• \text { At } ( 17,4 ) , m = - \frac { 1 } { 8 }
• \end{array}\)
• D) \(\begin{array} { l }
• m = - \frac { 1 } { 2 \sqrt { x - 1 } } \\
• \text { At } ( 17,4 ) , m = \frac { 1 } { 8 }
• \end{array}\)
• E) \(\begin{array} { l }
• m = - \frac { 1 } { 2 \sqrt { x - 1 } } \\
