Find (f•g)(x)=x^2-7x+12 and g(x)=3/x^2-16

Given f(x) = x^2 - 7x + 12 and g(x) = 3 / (x^2 - 16)

The product of the two functions, (f•g)(x) is equal to:

(x^2 - 7x + 12) * 3 / (x^2 - 16)

To simplify, factor the two polynomials:

x^2 - 7x + 12 = (x - 4 ) (x - 3 )

x^2 - 16 = (x - 4) (x +4)

=> (f•g)(x) = (x - 4)(x - 3) * 3 / [ (x - 4) (x +4) ] = 3 (x - 3) / (x + 4)

3 (x - 3) / (x + 4)

=

Dang i wish i could , good luck (i’m bad at math)

You can find the area of a rectangle by multiplying the length and height. so multiply 1/2*7/4(which is the simpler version of 1 3/4) and you get 7/8 as your answer.
