Given the function f(x)=(3x+-x) evaluate for f=5

22

Step-by-step explanation:

f(x)=(3x+4)-(2-x)

Let x =5

f(5)=(3*5+4)-(2-5)

     Do the parentheses first

    = (15+4) - (2-5)

     = 19-(-3)

     = 19+3

    = 22

For this case we have a function of the form , where:

Simplifying, taking into account that and , we have:

We add similar terms:

Now we evaluate the function at :
