Question

If f(x)=3x+4, what is f (x +2)?

Answer 1

Given :

f(x) = 3x+4

To Find :

f(x+2)

Solution :

f(x) = 3x+4

Finding zero of f(x) :

3x+4 = 0

3x = -4

x=-4/3

Then (x+2) =

$\frac{ - 4}{2} + 2 = \frac{ - 4 + 4}{2} = \frac{0}{2} = 0$

Then ,

f(x+2) = 3(0)+2 = 2

The required Answer is 2.

Answer 2

if f(x)=3x+4

f(x+2)=?

3(x+2)+4

3x+6+4

3x+10
