Question

If f(x) =
√2x+3
6x-5
a. 1
b. -2
then f() =
C. -1
d. - 13

Answer 1

Answer:

put 1/2as a value of x in the equation and then solve .then the answer will be -1

Answer 2

Answer:

$C.\ f\left( \frac{1}{2} \right) =-1$

Step-by-step explanation:

$f\left( x\right) =\frac{\sqrt{2x+3} }{6x-5}$

In order to calculate f(1/2) ,all we have to do

is replacing x by 1/2 in the expression of f.

Then

$f\left( \frac{1}{2} \right) =\frac{\sqrt{2\left( \frac{1}{2} \right) +3} }{6\left( \frac{1}{2} \right) -5 }$

        $=\frac{\sqrt{1+3} }{3-5}$

        $=\frac{\sqrt{4} }{-2}$

        $=\frac{2}{-2}$

        $=-1$
