Question 98

Multiple Choice

Find limh0f(x+h) f(x) h\lim _ { h \rightarrow 0 } \frac { f ( x + h ) - f ( x ) } { h } . f(x) =5xf ( x ) = 5 \sqrt { x }


A) limh0f(x+h) f(x) h=52x\lim _ { h \rightarrow 0 } \frac { f ( x + h ) - f ( x ) } { h } = - \frac { 5 } { 2 \sqrt { x } }
B) limh0f(x+h) f(x) h=72x\lim _ { h \rightarrow 0 } \frac { f ( x + h ) - f ( x ) } { h } = \frac { 7 } { 2 \sqrt { x } }
C) limh0f(x+h) f(x) h=32x\lim _ { h \rightarrow 0 } \frac { f ( x + h ) - f ( x ) } { h } = \frac { 3 } { 2 \sqrt { x } }
D) limh0f(x+h) f(x) h=52x\lim _ { h \rightarrow 0 } \frac { f ( x + h ) - f ( x ) } { h } = \frac { 5 } { 2 \sqrt { x } }
E) limh0f(x+h) f(x) h=72x\lim _ { h \rightarrow 0 } \frac { f ( x + h ) - f ( x ) } { h } = - \frac { 7 } { 2 \sqrt { x } }
