Find each value if fx=3x-4

63. f12

Short Answer

Expert verified

The required solution is f12=-52.

Step by step solution

01

– State the concept

The value of fa is given by putting x=a in the expression for fx.

02

– List the given data

The given function is fx=3x-4 and the objective is to find f12.

03

– Compute the required value

Put x=12infx=3x-4 to get,

f12=312鈭�4=32鈭�4=3鈭�82=鈭�52

So, f12=-52.

This is the required solution.
