Question

Find f(x)·g(x) if f(x) = 3x and g(x) = x + 1.
A. 3x2 + 3x
B. 3x + 1
C. 4x + 1
D. 3x2 + 1

Answer 1

is it B ?

Answer 2

No. sorry @Savannah2D0pe you have done somewhere wrong.

Answer 3

See f(x) . g(x) = 3x(x+1)

right?

Answer 4

yeah .

Answer 5

so 4x+1 ?

Answer 6

No : a(b+c ) = \(ab + ac\)

so \(3x ( x+1 ) = 3x (x ) + 3x(1) \)

^ That is called distributive property

Answer 7

i just dont get it ...

Answer 8

See :

\(a ( b + c ) = ab + ac\)

that is 3x(4x+1) = 3x*4x + 3x*!
