Question

Let F(x) =( 3x/2) - (14/3) for x = 4. What is the value for F(x)

Answer 1

Answer:

4 / 3

Step-by-step explanation:

Given,

x = 4

To find : F ( x ) = ?

Solution : -

F ( x ) = ( 3x / 2 ) - ( 14 / 3 )

F ( 4 ) = ( 3 * 4 / 2 ) - ( 14 / 3 )

= ( 3 * 2 ) - ( 14 / 3 )

F ( 4 ) = 6 - 14 / 3

LCM = 3

So,

6

= 6 / 1

= ( 6 / 1 ) x ( 3 / 3 )

= ( 6 x 3 ) / ( 1 x 3 )

= 18 / 3

F ( 4 ) = 6 - 14 / 3

= 18 / 3 - 14 / 3

= ( 18 - 14 ) / 3

F ( 4 ) = 4 / 3

Answer 2

Answer:

f(4) = 1.4

Step-by-step explanation:

f(x) = (3x/2) - (14/3)

We are given that x = 4

f(4) = (3(4)/2) - (14/3)

f(4) = (12/2) - (14/3)

f(4) = 6 - (14/3)

14/3 as a decimal is 4.6

f(4) = 6 - 4.6

f(4) = 1.4 (approximately)
