Question

What is the value of the function f(x)=3/2x-1/2 when x=6?

Answer 1

The correct answer is option 1

8 1/2

Explanation:

It is given that,

f(x) = 3x/2 - 1/2

We have to find f(x) when x = 6

To find the value of f(6)

we have, f(x) = 3x/2 - 1/2

when x = 6

f(x) = f(6)

f(6) = (3 * 6)/2 - 1/2

= 18/2 - 1/2

= (18 - 1)/2 = 17/2

= 8 1/2

Therefore the correct answer is first option

Answer 2

Option 1

Explanation:

In order to find the value of the function at x=6, we have to replace x by 6 in the given function.

`f(x)=(3)/(2)x -(1)/(2)`

Replacing(Substituting) x = 6 in above equation we get:

`f(6)=(3)/(2) (6) -(1)/(2)\\\\f(6)=9-(1)/(2)\\\\ f(6)=(18)/(2)-(1)/(2)\\\\ f(6)=(17)/(2)\\\\ f(6)=8(1)/(2)`

Thus, 1st option gives the correct answer.
