<em><u>2</u></em><em><u>.</u></em><em><u> </u></em><em><u>(</u></em><em><u>x-1</u></em><em><u>)</u></em><em><u> </u></em><em><u>;</u></em><em><u> </u></em><em><u>domain</u></em><em><u>:</u></em><em><u> </u></em><em><u>R-</u></em><em><u>(</u></em><em><u>-</u></em><em><u>4</u></em><em><u>)</u></em><em><u> </u></em><em><u> </u></em><em><u>{</u></em><em><u>all</u></em><em><u> </u></em><em><u>real</u></em><em><u> </u></em><em><u>number</u></em><em><u> </u></em><em><u>except</u></em><em><u> </u></em><em><u>(</u></em><em><u>-</u></em><em><u>4</u></em><em><u>)</u></em>

Step-by-step explanation:

f*g= f(x) and g(x)

i.e, f*g= (x^2+3x-4)(x+4)

i.e, f*g= x^3+3x^2-4x+4x^2+12x-16

i.e, f*g=x^3+7x^2+8x-16

it's domain is R, i.e, all real number!

f/g=(x^2+3x-4)/(x+4)

i.e, f/g={(x+4)(x-1)}/4

i.e,f/g=x-1

it's domain is all real number,except the number at which (x+4) becomes 0, i.e, x= (-4), -4 is not in domain!

First, let's convert X into 4

(3*4 - 4)ft,  (4*2 - 1)ft, (2*4*2 - 15)ft

Now lets simplify this a little

(12 - 4)ft, (8 - 1)ft, (16 - 15)ft

Awesome now lets finish up

8 x 9 x 1   /  2 = 36

The answer should be 36ft. Unless I did my math wrong.
