Question

.Given the function f(x)=(3x+4)-(2-x) evaluate for f=5

Answer 1

Answer:

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

Answer 2

For this case we have a function of the form $y = f (x)$, where:

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

Simplifying, taking into account that $- * + = -$and $- * - = +$, we have:

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

We add similar terms:

$f (x) = 4x + 2$

Now we evaluate the function at $x = 5$:

$f (5) = 4 (5) +2\\f (5) = 20 + 2\\f (5) = 22$

Answer:

$f (5) = 22$
